Match the types of roots to their properties. a root that is conical in shape and develops from the radicle a root that develops like a tuft of hair like roots and is short-lived a root that grows from plant parts other than roots a root that grows from branches to the ground a root that grow out of the soil adventitious root arrowRight pneumatophores arrowRight tap root arrowRight fibrous root arrowRight prop root arrowRight
Answer:
adventitious root ➡ a root that grows from plant parts other than roots
pneumatophores ➡ a root that grow out of the soil
tap root ➡ a root that is conical in shape and develops from the radicle.
fibrous root ➡ a root that develops like a tuft of hair like roots and is short-lived.
prop root ➡ a root that grows from branches to the ground
Explanation:
Adventitious roots are known to be roots that grow from a tree organ other than the root. The growth can be from the stem or leaf of that tree. This root makes it possible for vegetative propagation of plants to take place through stem or leaf cuttings. It can seen on rhizomes, corms, and tubers.
Pneumatophores are roots that grow out of the soil. They grow in saline mud and grow upward out of the mud and water. These type of root system are found in mangrove species. A tap root system is formed when the radical keeps growing and some other roots form along the tap root. They are conical in shape too.

In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X----------------Y-------------------------Z
20 m.u. 30 m.u.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 100%. When an F1 individual produces gametes, what proportion of its gametes would have xyz genotype?
a. 10%
b. 20%
c. 25%
d. 30%
e. 40%
f. 50%
g. 0%
h. None of these above
In F1 we will get 100% XxYyZz
each of these organism has two chromosomes that look like this
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
Those two chromosomes are homologous
we want a gamete that contains the second chromosome where crossing-over didn't occur. The distance between the genes of the chromosomes in map units is equal to the frequency of recombination in percentage. Therefore there is a 20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are
XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%
Since there is a 20% that the genes x and y will recombine that means there is a 80% chance that they won't and since there is a 30% chance that the genes y and z will recombine that means there is a 70% chance that they won't.
80%*70%=56% chances that the genes won't recombine. But, there are two non-recombinant gametes:XYZ and xyz therefore the chances for xyz is 56/2=28%
In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is: X----------------Y-------------------------Z, When an F1 individual produces gametes, we will get 100% gametes would have xyz genotype that is XxYyZz, it can be represented as
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
What is chromosome ?A chromosome can be observed as a thread-like structure present in the nucleus of cells such as plant, animal and human cells, composed of DNA (Deoxyribonucleic acid) molecule and histone proteins.
The three major components, DNA, proteins and RNA, the content of the DNA ranges from 30 to 40 % whereas proteins from 50 to 65%, and small amount of RNA ranges from 1 to 10%.
Two types of protein present such as histone and non-histones proteins, histone content is more (90% of total protein), whereas non-histone is content is less (around 10% of total protein).
The histone protein is basic, the DNA is acidic which can be neutralized; DNA is present in two forms such as Euchromatin and Heterochromatin.
20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%

Do you agree that wild species such as orangutans have the right to exist whether or not they are useful to humans? Explain.
Answer:
Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.
Explanation:
Hope this helps ;)
Ape like organisms with red coloured hairs that are mammals and belong to the Hominidae family are called Orangutans. They are found in the rainforests and are 1.2 - 1.8 m in height.
To this open question, I don't agree with the statement.
The viewpoint can be explained as:
They have the right to exist even when they are not useful to humans as they play a vital role in the food chain and the ecosystem in which they reside.If Orangutans are withdrawn from the ecosystem then many plant species will be impacted or can vanish.Orangutan helps in seed dispersion and sustain a healthy and balanced condition of the ecosystem.The residents, trees and the ecosystem are interdependent for survival and hence, they cannot be removed.To learn more about Orangutans follow the link:

Directions: Select the correct term or terms from the table. Different organisms have different traits, or characteristics. Some of an organism's traits are inherited from the organism's parents, while other traits are more strongly influenced by the organism's environment. Among most animals, which of the following traits are usually directly determined by genes inherited from the organism's parents? sex body weight knowledge blood type
Answer:
The correct answer is - sex and blood type.
Explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.
Which of the following animal welfare practices would be most useful for reducing disease?
giving animals more space
supplementing the animals’ feed
adding environmental enrichments
changing how animals are handled at slaughter
Answer:
The answer is "supplementing the animals’ feed"
Explanation:
Animal welfare implies how a creature is adapting to the conditions in which it lives. An animal is in a decent condition of welfare on the off chance that it is solid, agreeable, very much fed, protected, ready to communicate intrinsic conduct, and on the off chance that it isn't experiencing disagreeable states, for example, torment, dread, and pain. Great animal welfare requires infection avoidance and veterinary treatment, proper asylum, the board and sustenance, sympathetic taking care of and empathetic butcher or murdering
Answer:
giving animals more space
Explanation:

There are three alleles for the ABO blood group in humans. Why are there only two alleles normally present in any individual?
1. The alleles for the ABO blood group always segregate independently during meiosis.
2. Each parent contributes only one allele for the ABO blood group to the offspring
3. Every gene for the ABO blood group must be recessive.
4. The alleles that determine the ABO blood group are on the X-chromosome.
Answer:
2. Each parent contributes only one allele for the ABO blood group to the offspring
Explanation:
Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.
Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.
A. If you have several samples of liquid and are told that one contains living organisms,
what type of in vestigation would you do to determine which liquid contains the living
things?
Answer: (Aerobic and anaerobic respiration)
Explanation:
Respiration by living organisms can be investigated by carrying out experiments to show the production of carbon dioxide and heat.
Investigating carbon dioxide production
Limewater turns milky in the presence of carbon dioxide. It can be used to show that exhaled air contains more carbon dioxide than inhaled air.
Carbon dioxide dissolves in water to form a weakly acidic solution. Hydrogencarbonate indicator is used to show the presence of carbon dioxide in solution. It is:
red at neutral pH (no carbon dioxide)
yellow at low pH (carbon dioxide present
How could you decrease the amount of energy an object has?
The amount of energy that an object has can be decreased by decreasing its temperature.
Let us recall that the temperature of a body is a measure of the average kinetic energy of the molecules of the body. The molecules in a body are always in constant random motion.
The kinetic energy possessed by the body is dependent on its temperature. To control the amount of energy that an object has, we either increase or decrease its temperature.
If we want the amount of energy that an object has to decrease, we simply decrease its temperature.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

How can you use isobars to determine approximate wind speed and direction using the pressure map?
Answer:
Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.

In the past 250 years how many volcanoes have erupted?
Answer:
Graph showing known historically active volcanoes, number of volcanoes reported to be active each year, and population. The line labeled "Known Historically Active Volcanoes" (right scale) is the cumulative number of volcanoes with an historically recorded eruption by that year. "Volcanoes Active Per Year" since 1400 CE (black line) and 10-year running mean of same data (thick red line) is also based on reported eruptions (those with uncertainty dates greater than 1 year are not included, nor are uncertain eruptions). "Population" (right scale) is the world's estimated human population; data from McEvedy and Jones (1978) and (since 1750) Population Reference Bureau, Washington, D.C. See text for further explanation.
A dramatic increase in both the number of historically active volcanoes and recorded eruptions took place about 1500 CE. These resulted in part from the great Spanish/Portuguese marine explorations – the Age of Discovery – around the end of the 15th century, when explorers opened Latin America and much of the western Pacific to European record-keeping. Perhaps equally important was the development and widespread distribution of the printing press in the late 15th century, markedly increasing the likelihood that new volcanological records would survive. Through the 17th and into the early 18th century the recognition of additional active volcanoes generally corresponded with steadily increasing eruption reports. By the 18th century global trade was flourishing, the Industrial Revolution was under way, and the heightened reporting of eruptions noticeably accelerated the discovery of new volcanoes. The list has continued to grow, with several important volcanic regions such as New Zealand, Alaska, and Hawaii being unrepresented until the last 250 years.

Which of the following is a peptide bond?
A.C-H bond
B.N-H bond
C.C-C bond
D.C-N bond
Answer:
The correct answer is - D.C-N bond
Explanation:
A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.
So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.
So the peptide bond that formed by this reaction is involve bonding of C-N bond.
