Two different groups of scientists studying a rare trait in ground squirrels report very different heritabilities. What factors influencing heritability values make it possible for both conclusions to be correct?

Answers

Answer 1

Answer:

It is a trait highly influenced by environmental factors (i.e., it has low heritability)

Explanation:

In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.

what is the last thing that happens when a cell divides to produce two new identical cells

Answers

Answer:

The last phase of cell division is cytokinesis. In this phase the cytoplasm of parent cell divides in to two cells called as daughter cells. It occurs during late stages of nuclear division.

The visible change of cytokinesis in an animal cell can be observed as formation of Furrow or Pucker on the cell surface.

Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.

Answers

Answer:

The bipedality

Explanation:

One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.

NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment

.-Birds migrating when seasons change.

The maintenance of relatively constant internal environment of an organism is called  Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.

The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the  homeostatic control.

The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors  send signals to the brain ,and the organisms  responded to these with the example above.

How does the formation of NAD+ differ between aerobic and anaerobic respiration?

A. NAD+ is formed in aerobic respiration by a fermentation process and formed in anaerobic respiration by oxidation of NADH.

B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.

C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.

D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.

Answers

Answer:

B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.

Explanation:

Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.

The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?

Answers

Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

Explanation:

Phospholipids, triglycerides, fats, and oils are examples of a lipid. Therefore, option D is correct.

What are lipids?

Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.

Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.

Cell membranes, cholesterol, blood cells, and the brain are just a few places where they can be found in the human body.

WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?

The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.
