Explanation:
In pea plants yellow seeds are dominant to green seeds. A plant with green seeds cross at the plant that is heterozygous.
What are the alleles?
What are the genotypes of the parents?
What are the F1 genotypes?
F1 phenotypes?
Answer:
The correct answer is -
1. Y (yellow) and y (green)
2. Yy (yellow dominant) and yy (green)
3. Two heterozygous yellow (Yy) and two green recessives (yy)
4. 50% Yellow and 50% green plant
Explanation:
In the given question, it is given that a pea plant has two alleles for the trait yellow seeds and green seeds, the alleles for the traits are green (y) and Y for the dominant trait.
The cross between the green seed (yy) pea plants, is recessive and heterozygous which means a combination of dominant and recessive are as follows:
Y y
y Yy yy
y Yy yy
Here two heterozygous yellow seeds and two recessive green seed plant offspring.
Assume that you now study a third gene having alleles C and c. For each genotype, what type(s) of gametes will be produced
Complete question:
One gene has alleles A and a. Another has alleles B and b. Assume that you now study a third gene having alleles C and c. For each genotype, what type(s) of gametes will be produced
a. AABBCC
b. AaBBcc
c. AaBBCc
d. AaBbCc
Answer:
a. ABC
b. ABc, aBc
c. ABC, aBC, ABc, aBc
d. ABC, ABc, AbC, Abc, aBC, abC, aBc, abc
Explanation:
We have three genes that are not linked. Each gene can be in a dominant form or a recessive form. (A and a, B and b, C and c). Gametes are haploid sexual cells, n, meaning that they have half of the genetic material of a diploid cell. When two gametes get together, they form a diploid cell, the zygote.
As these genes are not linked, they segregate independently from each other. According to this, we can assume different allele combinations of these genes that form the gametes.
To know what kind of gametes might be formed from these genotypes, we just need to think about all the possible combinations according to the alleles of each gene. A gamete needs to have one allele of each gene.
An easy way to do so is to analyze genes separately and the possible combinations.
Genotype Possible alleles combination Gametes
a. AABBCC A----B----C ABC
In this genotype, there are only dominant alleles for each gene, so there is only one possible combination of alleles. A with B and C
b. AaBBcc A----B----c ABc
a----B-----c aBc
For this genotype, gene A has the dominant allele and the recessive one (A and a, respectively). Gene B has only dominant alleles (BB), and gene C only recessive alleles (cc). So we have two possible allele combinations: "A" with "B" and "c", and "a" with "B" and "c".
c. AaBBCc A----B-----C ABC
A----B-----c ABc
a-----B-----C aBC
a-----B-----c aBc
For this genotype, gene A has the dominant allele and the recessive one (A and a, respectively). Gene B has only dominant alleles (BB), and gene C has the dominant allele and the recessive one (C and c, respectively). So we have four possible allele combinations: "A" with "B" and "C", "A" with "B" and "c", "a" with "B" and "C", and "a" with "B" and "c".
d. AaBbCc A----B----C ABC
A----B-----c ABc
A-----b-----C AbC
A----b-----c Abc
a----B-----C aBC
a----B------c aBc
a-----b-----C aBC
a-----b-----c abc
This is a complete heterozygous genotype, which means that we have two options for each gene: the dominant allele and the recessive one. We have eight possible allele combinations.

The Scarlet King Snake is a non-poisonous snake. It intentionally looks like the poisonous Eastern Coral Snake in order to scare away predators. What is this type of animal adaptation called?
A) camouflage
B) hibernation
C)migration
D) mimicry
Answer:
mimicry
Explanation:
Mimicry, in biology, phenomenon characterized by the superficial resemblance of two or more organisms that are not closely related taxonomically. This resemblance confers an advantage—such as protection from predation—upon one or both organisms by which the organisms deceive the animate agent of natural selection.
okay, the answer is D. mimicry. i mean- think about it: it cant be camouflage because like- camaflouge is where they hide like the stick bug. the stick bug camouflages into the tree. like- the stick bug has the same detail, looks like the tree. so it cant be camouflage. it cant be hibernation because snakes dont hibernate only fur animals do. snakes have scales. it cant be migration because only insects like butterflies, birds, and so on, only they migrate. snakes dont have wings. now we are left with D. if you think its A or D it can be but its D i got an A+ on my test with this question.
by what factor would the rate of diffusion across a membrane change if both its area and thickness doubled
Answer:
Size of particle.
Explanation:
Size of the particles that are diffusing is the factors that greatly affect the rate of diffusion. The rate of diffusion decreases if the thickness of the membrane becomes doubled while on the other hand, if the surface area of the membrane increases it doubled the rate of diffusion of the cell. If the size of particles is very small so it will diffuse if the membrane has double thickness.

What process takes advantage of these microbes' abilities, by growing the them in the presence of the enzyme's substrate, allowing the microbe to catalyze the step needed to produce some industrial products
Answer:
Metabolic Engineering
Explanation:
Metabolic engineering refers to the process of modifying the genetic and enzymatic processes within cells in order to optimize the output of products. When constraints are noticed in the normal biological process, scientists endeavor to modify the constraints so that wide scale production can be realized.
Examples of processes that incorporate this technique are beer, cheese, wine and some drugs production.

What is the movement of air during the day where land and water meet?
Answer:
from water to land
Explanation:
during the day a land has higher temperature than water so the air is lighter on land and makes space for heavier one from water. that's why the air moves from water to land
the movement of air during the day from water to land
what are the properties of water ?The physical property of Water are, it is a colorless and tasteless liquid, have extensive hydrogen bonds resulting in unusual properties in the condensed form.
This also have high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment, etc.
Water is a great solvent and helps in the transportation of ions and molecules required for metabolism, has high latent heat of vaporization helps in the regulation of body temperature.
It is Amphoteric nature can act as both acid and base means that it is amphoteric in nature, it is Electropositive elements which reduce water to hydrogen molecule and it is the source of hydrogen.

When hydrogen is broke down what 2 substances are created
When hydrogen is broke down 2 isotopes of hydrogen are created.
Why is hydrogen present in combined form?When atoms of the same or different types combine, molecules form. As a result, two Hydrogen atoms join together to form a Hydrogen molecule.
Hydrogen is mostly found in the combined state, such as water, rather than in the free state.
An atom of hydrogen, on the other hand, rarely exists on its own because its unpaired electron is always looking for a partner. Hydrogen in its molecular form is more common.
Each hydrogen isotope contains only one proton, but they differ in the number of neutrons in their atoms.
Because of the extra neutrons, the isotopes become heavier: deuterium is twice as heavy as ordinary hydrogen (also known as protium), and tritium is three times as heavy.
Thus, isotopes of hydrogen, i.e., protium and deuterium will be created.

Describe how the Punnett square is a mathematical model for predicting
outcomes of inheritance patterns.
Answer:
Punnett squares are used to show all of the combinations of alleles that might result from across and the likelihood that each might occur.
Explanation:
Punnett squares are diagrams used by biologists to determine the probability that offspring have a particular trait. The creation of Punnett Square and its use to determine the characteristics of offspring is called the performance of the cross.
The crosses in Punnett Square are based on meiosis, a biological process in which parents transmit alleles to gametes, which they later pass on to their offspring. Each parent has two alleles for the trait and passes one to their offspring. Each offspring completes a total of two alleles, one from each parent.

2. While gazing into an aquarium, you see bubbles coming from an aquatic plant . What are the bubbles
Answer:
oxygen bubbles
Explanation:
These bubbles are oxygen bubbles that are being produced by the aquatic plants at the bottom of the aquarium. As oxygen usually does it floats to the top of the water and back up into the atmosphere. This happens because of the photosynthesis process in which the plants soak up sunlight and carbon dioxide and uses it to produce and release oxygen. Since this process happens underwater for the aquatic plants the oxygen become bubbles and float up.

#CARRYONLEARNING #STUDYWELLwhat is a company's obligation to contribute to the sustainability of natural resources?
Answer:
Under law? Depending where and what biz is there is NO obligation, or little if any in most cases.
Under morals, aka higher principles most bussinesses would just have to close.
Under Biblical principles, to subdue is one thing, to destroy is another. Much can be done but won't be because of cost/politics over logic. Sometimes that too is a natural resource, it's called freedom and or liberty and someone is using a lever for an alternate motive just saying it's for the 'trees’. Other cases it's plain and clear destruction for profit and nothing is said.
Record forest fires have occurred in west, some of it because environmentalists interfered with forest management to the point of cost in court and in the field leaving nothing to do. Areas that needed undergrowth and deadwood removed were kept untouched decades. Red tape and global warming made fuel stack up.
If solution A has a pH of 2 and solution B has a pH of 8, which of the following statements is true?
a.A has a greater [OH-] than B.
b. A is acidic and B is basic.
C.A is a base and B is an acid.
d.None of these
e. A is basic and B is acidic.
Answer: b. A is acidic, B basic
Explanation: pH 7 is neutral, with equal H+ and OH-
pH is -log(H+ Molar Concentration) and at pH7, H+ and OH- are both at a concentration of 10^-7
A more acidic solution has more H+ than OH-, so it is a higher concentration than 10^-7 and therefore pH lower than 7. Conversely, a pH>7 means a higher concentration of OH- and lower concentration of H+
Considering the definition of pH, the correct statement is option b. A is acidic and B is basic.
You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The scale has values ranging from 0 to 14, with pH 7 being the neutral solution. Solutions with pH less than 7 are acidic and alkaline (basic) those with pH greater than 7.
Then, being the pH of solution A equal to 2, being less than 7, the solution is acidic. On the other hand, the pH of solution B is 8. As the pH is higher than 7, solution B will be basic.
So, finally, the correct statement is option b. A is acidic and B is basic.
