What determines which bases will be brought to the DNA strand during DNA replication?

Answers

Answer 1
Answer:
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

WHY IS A FOSSIL FOUND IN MULTIPLE LAYERS OF ROCK (TIME PERIODS) NOT CONSIDERED A RELIABLE INDEX FOSSIL?

Answers


Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.

How could one determine if two
unidentified organisms share a common
ancestor?

Answers

Answer:

Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.

Explanation:

DNA

They can look at the DNA it's the most common one.

There are 4 pieces of evolution and they are

Fossils , Geography , Embryos / DNA , Anatomy

Fossils: Physical remains of species , Determine age, location,  environment

Deeper layers = older

Geography: Proves species share common  ancestors, depending on where

they live

DNA: BEST evidence because it’s the  MOST ACCURATE

Similarities in the early stages of  development

Similarities in DNA

More similarities = closely related

More differences = not related

Anatomy: Compare body parts of different  species to see how they evolved

3 different structures:

Homologous (same structure,  different function)

Analogous (similar structure,  different organisms)

Vestigial (body parts that no  longer serve a purpose)

All of that are in evolution

Salmonella infection and campylobacteriosis cause diarrhea after eating partially cooked chicken. This causes food poisoning.

What is food poisoning?

An illness called food poisoning is brought on by consuming tainted food. Most people recover without treatment in a few days and it's typically not dangerous. The food is typically contaminated with bacteria, such as salmonella or Escherichia coli (E. coli), or a virus, like a norovirus, in cases of food poisoning.

more than three days of diarrhea. A high fever (102°F or above) vomiting so frequently that it is difficult to swallow liquids. Dehydration symptoms include not peeing as frequently, a dry mouth and throat, and feeling lightheaded while standing up.

Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens

Answers

All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.

The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.

Hence, all of the statements correctly identify a lymphatic organ.

How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)

Answers

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

students observed several prepared slides of a process that occurs in a dividing onion cell. they observed haploid cells in one slide, centromeres that did not separate during anaphase in another slide, and two different cell divisions resulting in 4 daughter cells in other slides. Which statement is not true about the process that was observed?
1.) the slides were of an egg cell or sperm cell
2.) the process observed produce genetically different cells
3.) the number of chromosomes resulting from the process is reduced by half
4.) the observations suggest cellular reproduction and general growth and repair of the body.

Answers

Answer: pretty sure it could be “B”.

Explanation:

Meiosis produces 4 haploid cells -gametes- from a single diploid cell. The statement that is not true is 4).  the observations suggest cellular reproduction and general growth and repair of the body.

Observed prepared slides:

haploid cells in one slide.centromeres that did not separate during anaphase in another slide.cell divisions resulting in 4 daughter cells in other slides.

According to this information, we can assume that the students are observing the occurrence of meiosis events.

Meiosis

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n). Thes haploid cells are the gametes.

After DNA replication there are two meiotic phases.

The first one is a reductive phase, in which homologous chromosomes separate.

In the second phase, the cell suffers a new, not reductive division.

1. In the first phase, Meiosis I:

Prophase I: Chromosomes condensate and become visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one.

Metaphase I: Homologous chromosomes randomly align in the equatorial plane.

Anaphase I: In this phase occurs the division and independent separation of homologous pairs. Each chromosome migrates to different poles. This separation generates different chromosomal combinations in the daughter cells.

Telophase I: Chromosomes of homologous pairs are already in the corresponding poles, and the nuclear membrane forms again in each pole.

Cytokinesis occurs.

2. In the second phase, Meiosis II:

Prophase II: Chromosomes condensate again and become visible.

Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase.

Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole.

Telophase II: Once in the poles, the chromosomes become lax again, and the nuclear membrane forms again.

Cytokinesis occurs.

Options

1.) the slides were of an egg cell or sperm cell ⇒ Correct. It makes reference to gametes -haploid cells-.

2.) the process observed produce genetically different cells ⇒ Correct. After crossing over and independent segregation of chromosomes.

3.) the number of chromosomes resulting from the process is reduced by half ⇒ Correct. After the reductive phase.

4.) the observations suggest cellular reproduction and general growth and repair of the body. ⇒ INCORRECT. Mitosis is in charge of general growth and repair of the body, not meiosis.
