Answers

Answer:

Centromere

Explanation:

Connects sister chromatids

The structure labelled A in the figure is a centromere.

What is a centromere?

The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.

The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.

Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted

The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

what was the speed of a car that traveled 240 m in 12 s

Answers

Answer:20

Explanation: Because when you divied 240 by 12 you get 20.

240/12=20

Answer:

20m/s

Explanation:

Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

These conditions are:

1. There is noo mutation,

2. Existence of random mating,

3. There should be no natural selection

4. There is the infinite population size

5. No migration

Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium

What 3 types of science formed the geological time scale?

a) archaeology, paleontology, astrology
b) Scientology, astronomy, and geology
c) geology, archaeology, and paleontology
d) paleontology, Scientology, and biology

Answers

Answer: c) geology, archaeology, and paleontology

Explanation:

The geological time scale can be defined as a scale which is used to determine the chronological dating of the organisms in the geological strata. It helps in determining the occurrence and existence of particular kind of species on planet earth. It can also be used to trace the development and passage of a particular kind of trait from one generation to the another. It can also be used to trace back various geological events that occurred on planet earth like volcanic eruption, plate tectonics, and others. The geologists used it for tracing the geological activities that occurred in the history of earth. Archaeologist study about rocks and fossils to trace back the geological time scale. Paleontologist study the existence of a particular species via studying the fossil evidences and reconstructing the primitive conditions by developing a geological time scale. They trace the evolutionary history of organisms.

Answers

Answer:

1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II

● PhotosystemSII acts first during the light transformation process in photosynthesis.

● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from

plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.

Which of the following correctly explains the differences between artificial and natural selection?

Answers

Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

prostate cells usually require testosterone and other androgens to survive. but some prostate cancer cells thrive despite treatments that eliminate androgens. one hypothesis is that estrogen, often considered a female, may be activating genes normally controlled by an androgen in these cancer cells. desribe one or more experiments to test this hypothesis

Answers

One can check for the translation and transcription of genes of interest in the absence of androgens, one can check whether the estrogen is involved in the expression of oncogenic proteins of interest by depleting the estrogen, and one can also examine the existence of estrogen receptor complex in the prostrate cancer cells nuclei.

• One can check for the translation and transcription of genes of interest in the non-existence of androgens and if these genes are expressed then this suggests that apart from androgens other factors also affect their expression.

• One can deplete the estrogen from cancer cells and if the involvement of estrogen is there in the expression of oncogenic proteins of interest then its reduction will result in diminished multiplication rates in cancer cells.

• One can also test the existence of estrogen-receptor complex in the prostate cancer cells nuclei to confirm that estrogen is taking part in the regulation of gene expression.

Thus, various experiments can be conducted to check that whether the expression of genes controlled by the androgens under normal conditions are affected by the presence of estrogens in prostate cancer cells.

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?

Answers

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

What does glycolysis process?

Glycolysis is the method of breaking down glucose. Glycolysis can take place with or without oxygen. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water.

Glycolysis occurs in the cytoplasm.

Which are ways that humans can lower biodiversity as they us environment? Check all that apply. A. Converting a forest to soccer fields B. Spraying pesticides on lawns An C. Building roads across tundra D. Replacing riverbanks with concrete bulkheads and

Answers

Answer:

A, B, C, and D

Explanation:

All of the options represent ways by which humans can lower biodiversity as they use the environment.

By definition, biodiversity or biological diversity of an area refers to the total number of living organisms that are domicile in that area.

Converting a forest to a soccer field requires that the variety of plants and animals in the forest are removed and the forest soil is planted with turfs in their place. Thus the biodiversity of the forest has been greatly reduced in other to pave way for a soccer field.

A pesticide is an agrochemical that kills pests. Pests are biological organisms even if they are not that desirable on the lawn. Thus, killing them off using a pesticide is a way of reducing the biodiversity associated with the lawn.

A tundra represents an ecoregion with its own characteristic plants and animal, even if they are few. Hence, building roads across tundra requires that portions of the biodiversity are removed to pave way for the road.

Riverbanks serve as habitats for a variety of living organisms. Replacing them with concrete bulkheads means that the habitat is lost and the organisms displaced. Thus, the biodiversity of the region gets reduced.

Therefore, options A, B, C, and D are all correct.
