Legend has it that there was a less famous geneticist in the 1800s
named Megor Grendel. He did his experiments with the cats that lived in the monastery's barn. Here are some results from one of his 16 crosses:
Cross #3 Maggie (orange) x ? (possibly Tom, or maybe Bill)
Kittens:
1. light orange female
2. dark orange male
3. black female
4. light orange female with white paws
5. black male with white paws
6. orange ? (sex undetermined; died at birth)

Answers

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

The researcher has total control over the crosses. Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible. Pea plants may be examined for a greater series of generations than cats or other animals. Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism. Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern. Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

Which of the following best describes why we see different moon phases?

A. The moon revolves around the Earth once a month.
B. The earth revolves around the moon once a month.
C. The amount of sunlight hitting the moon changes over time.
D. The earth revolves around the run once a year. (This one ??)

Answers

Answer:

It's C.

Explanation:

What we see as phases of the moon is the reflection of sunlight bouncing off the moon's surface.

We see different moon phases because the moon revolves around the Earth once a month.

FACTS ABOUT THE MOON:

The moon is the only satellite that the Earth has. The rotation of the moon around the Earth makes us experience day and night.

The moon as a celestial body does not possess a light of its own, hence, the light we see when looking at the moon is that from the sun.

It takes a month (about 27 days) for the month to complete its evolution around the Earth. Hence, we see different phases of the moon based on the part of the moon being lit by the sun.

This different phases of the moon we observe is only possible because the moon revolves around the Earth once a month.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen

Answers

Answer:

Explanation:

Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily.  These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.

Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.

Of the 23 pairs of chromosomes in any normal human cell, the first ____ pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's _____________ can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.

Answers

Answer:

Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.

Explanation:

Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.

The correct fillers for the given statements are: "22" and "personality and cognitive abilities"

Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.

Humans have 23 chromosome pairs in their cells, one out of 23 pairs is responsible for the gender of the human embryo or child.the other initial 22 pairs are responsible for providing directions for an individual's body and brain development.On the basis of studies, many scientists say that almost half of the traits of personality and cognitive activities or mental processes to learn or acquire activities are due to chromosomes.

Thus, the correct answers are : "22" and "personality and cognitive abilities"

B. Mutations in sex cells can be passed on to children.
c
C. Mutations in sex cells are chromosomal mutations.
a
D. Mutations in sex cells are silent mutations,

Answers

Answer:

B

Explanation:

B

A mutation in a sex cell (sperm or egg cell) differs from a mutation in a non-sex cell (somatic cell) in several ways: . Mutations in sex cells can be passed on to children and Mutations in sex cells are chromosomal mutations and may more.

How are mutations can be passed on to children ?

Mutations in sex cells can be passed on to children: When a mutation occurs in a sex cell, it can be passed on to the offspring and become a hereditary condition. On the other hand, mutations in non-sex cells cannot be passed on to offspring.

C. Mutations in sex cells are chromosomal mutations: Sex cells contain chromosomes, and mutations in these cells can result in chromosomal abnormalities that can affect the development and health of the offspring.

Thus, A and D are incorrect. Mutations in sex cells are not necessarily more deadly than mutations in non-sex cells, and they are not always silent mutations. The effects of a mutation depend on its location and the function of the gene affected.

Answers

Answer:

If one link is stop working.

Explanation:

There are six points at which the chain of infection can be broken or interrupted and a germ can be stopped from infecting another people. The six links are the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. If one of the link is broken or interrupted, no infection occurs in the body of an individual because all the links are attached to each other in the form of chain which can stop working if one of it stop working.

High altitude adaptation is a complex physiological process that involves an increase in both the number of Hb molecules per erythrocyte and the total number of erythrocytes. It normally requires several weeks to complete. However, even after one day at high altitude, there is a significant degree of adaptation. This effect results from a rapid increase in the erythrocyte BPG concentration.


a. Try to do this without looking at the graphs. If oxygen-binding curves for both high altitude adapted hemoglobin and normal, unadapted Hb were plotted together, would the curve for high altitude adapted Hb be to the left of, to the right of or the same as the curve for unadapted Hb? Explain.
b. Is the oxygen binding affinity of high-altitude adapted Hb higher, lower, or the same as that of unadapted Hb? Explain.

Answers

Answer:

a. To the right

b. higher

Explanation:

From the information given:

a.

The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.

b.

As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.

Lindeman gave the 10% law which means at each step of the food chain when food energy is transferred from one trophic level to the next trophic level, only about 10% of energy is passed on to the next trophic level.

Producers (100%) → Primary consumer (10%) → Secondary consumer(1%) → Tertiary consumer (0.1%).

Therefore, If producers receive 1,000kcal of energy from the sun, the energy received by the tertiary consumers in that energy pyramid is 1kcal.

what are some of the actions that the somatic nervous system does?

Answers

Mark Brainliest please

Answer

It regulates voluntary activities.
It relays information to and from skin and skeletal muscles

Explanation

The somatic nervous system is part of the peripheral nervous system (part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs). It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).

The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).

The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat
