what does DNA looks like? describe the structure of DNA?​

Answers

Answer 1
The DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands

Answer:A

Explanation:

The meaning of evolution-the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

So, B is incorrect since it is talking of the present. C, shows the growing of hair, but has no answer to evolution, since it does not show an organism growing from the past to present. D, shows evolution of land but no “living organism”

A student uses a microscope to observe cells in the root tissue of an onion. He
concludes that the cells are reproducing by mitosis.
Which hypothesis is supported by his conclusion?
a. The root tissue cells all have the same set of chromosomes.
b. The root tissue cells each have a unique genetic make-up.
c. The root tissue cells produce identical gametes..
d. The root tissue cells split to form stem cells.

Answers

The correct answer is option a. The root tissue cells all have the same set of chromosomes as it clearly explains the hypothesis.

Onions (Allium cepa L.) have eight relatively large chromosomal pairs (2n = 16) that can easily detect CA.

Mitosis creates two identical daughter cells, each containing the same number of chromosomes as the parent cell. In contrast, meiosis produces four unique daughter cells, each with half the number of chromosomes in the parent cell. Therefore, during the mitotic cell cycle, the DNA content per chromosome doubles in the S phase (each chromosome begins as a chromatid and becomes a pair of identical sisters in the S phase). However, the number of chromosomes remains the same.

How many chromosomes do cells have after the G1, S, and  M phases?

Onion root cells have chromosome 16  in each cell after the G1, S, and  M phases.

Thus it concluded that mitosis causes root tissue cells to all to have the same set of chromosomes.

Answer:

Periods of light-timeTemperatureSubstrate/Soil type

Explanation:  

Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.

These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.

All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.

define homologous structure in YOUR OWN WORDS

Answers

Answer:Homologous structures are similar structures that evolved from a common ancestor. Learning Objectives. Describe the connection between evolution and the appearance of homologous structures.

Explanation:A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.

The process of osmosis is best illustrated by the movement of a. water into root hair cells b. oxygen intro red blood cells c. carbon dioxide through stomates d. glucose through phloem

Answers

Answer:

a. water into root hair cells

Explanation:

Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a semi-permeable from a region of high concentration to a region of lower concentration.

Hence, the process of osmosis is best illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.

feedback mechanism

Explanation:

Feedback mechanism: In biology, the term "feedback mechanism" is described as a physiological loop that is responsible for bringing up the body either away or towards the steady or normal state. The feedback mechanism is also denoted as "feedback loop" and is responsible for either inhibiting or amplifying a specific biological pathway. Therefore, these pathways tend to return the body towards "homeostasis".

In the question above, the given statement is an example of a "feedback mechanism".
