John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant

Answers

Answer 1

Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.

John's genotype with unattached being dominant is Aa.

Using A to represent the allelesSince his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa). So for John to have an unattached earlobe, his father has to be either AA or Aa. Therefore John's genotype would be Aa

Answer:

The answer is C.) 1953, Watson and Crick. In 1953, with the help of Rosalind Franklin, Watson and Crick discovered the structure of DNA.

Explanation:

To be specific, James Watson and Francis Crick were the first people to make a 3-D model of DNA. Although it may not seem much today, as our technology has advanced so much ever since, it was big time in 1953. They discovered that DNA was shaped like a double-helix, or twisting ladder.

Answers

Answer:

(A) The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.

Explanation:

The vertebrate and many of the other parts of the skeletal structure of the gorilla and chimpanzee are alike. (and, by using a little background knowledge, you can figure this out by thinking; if humans share 98% of DNA with chimpanzees and about 96% of DNA with gorillas, then the two animals must share a lot of DNA as well.)

I hope this helps !!!

Answer:

1, 3, 4

Explanation:

The gorilla and the chimpanzee have very similar anatomy, so they are closely related.

There is a small resemblance between the dog and the frog, but nowhere close to the one shared with the gorilla and chimpanzee, so NO

the dog IS more closely related to the frog than the chimpanzee since it looks more similar

yes, all of them are vertebrates and therefore share a single vertebrate ancestor

How would the carbon cycle be influenced by an increase in aerobic respiration?

Answers

Answer:

Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).

Explanation:

Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.

Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.

Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.

Answers

Answer:

The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced

Explanation:

Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.

Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.

High blood pressure occurs when there is too much blood flowing through the blood vessels at one time. By changing the amount of water in the blood, blood pressure can change. The excretory system can help to lower blood pressure.

Which would most likely occur in the kidney?

More water would be transferred from the nephron.
Less water would be absorbed into the nephron.
The amount of water in the bladder would decrease.
The amount of water in the blood would increase.

Answers

Answer:

c

Explanation:

The kidney plays an essential role in regulating blood pressure by adjusting the volume and concentration of water and solutes in the blood. Therefore, to lower blood pressure, Less water would be absorbed into the nephron. Hence option B is correct.

What is a nephron?

The nephron is the functional unit of the kidney that is responsible for filtering waste and excess water from the blood. When there is an excess of water in the blood, the kidney can decrease the amount of water that is reabsorbed into the body.

This would result in more water being excreted from the body in the urine, reducing the volume of blood and lowering blood pressure.

To achieve this, the kidney reduces the secretion of antidiuretic hormone (ADH) or vasopressin, which controls water reabsorption in the kidneys.

This decrease in ADH secretion causes the nephrons to reduce the amount of water they reabsorb from the urine, leading to an increase in urine output and a decrease in blood volume.

Therefore option B Less water would be absorbed into the nephron is correct.

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Uplift and formation of a mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the mountain range and brings the two populations together again, but when they mate, the resulting hybrids have sterile young. This is and example of which type of reproductive barrier

Answers

Answer:

Post reproductive isolation → Hybrid sterility

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.    

In the exposed example, sympatric speciation occurs. It seems that the mountains separating the snails´ populations made a place for speciation and the development of postzygotic barriers, specifically hybrid sterility. After the erosion process, both populations got to meet again. Snails from one population get to mate and produce offspring with the snails of the other population, but their progeny is sterile.

Amoeba sisters video recap Biomagnification

Answers

I suggest you watch the Amoeba Sisters video again, 1-2x and take notes.

Biomagnification is when toxins / heavy metal are present in small amounts in fish, but accumulate as you move into higher trophic levels. This is one reason why it can be toxic for humans to eat tertiary or quaternary consumers, such as swordfish, shark, etc.

Biomagnification refers to the presence of higher concentration of chemical toxins as a result of the accumulation of toxins in organisms.

What is biomagnigication?

Biomagnification is best explained as a condition in which the chemical concentration of a toxin is amplified in an organism compared to the environment in which the organism is found.

Biomagnification usually is observed as one goes higher in the trophic levels of organisms.

For example, chemical pollutant found in water may be present at tolerable levels. However, in organisms, living in the water, the concentration of the pollutant is higher as these organisms accumulate these toxins in their tissues.

Therefore, biomagnification refers to the accumulation of toxins in organisms higher than found in their environment.

scientists believe the earth likely warmed between 0.65 celsius and 1.05 celsius with an average value of 0.85 celsius between years 1880 and 2012. what was error bar for the increase in temperature over that period?

Answers

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.
