In meiosis 4 cells are created and are unique. What process causes this genetic variation?

Answers

Answer 1

Answer:

Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA.

………….what are alveoli

Answers

Answer:

Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body. Carbon dioxide travels in the blood from the body's tissues and passes through the alveoli to be breathed out.

What enzyme opens up in the DNA into two single strands ?

Answers

Answer:

DNA helicase

Explanation:

The image of this question shows the replication of DNA into two identical copies. However, before this occurs, the double-stranded DNA needs to be unwound or separated so that each single strand can serve as a template for a new strand.

An enzyme called DNA helicase is responsible for the separation of the DNA molecule into single strands. After which, DNA polymerase begins to add nucleotides to each single strand of DNA.

Photophores help the animals which zone of the ocean? How do they help?

Question 6 options:

coasts - tentacles to attach to rocks

frozen ocean areas - help blood from freezing

deep sea areas - attract prey with light

coral reef areas - calcification for skeletal protection

Answers

Answer:

Deep Sea Areas

Explanation:

Photophores are animals that produce light.

Photophores help the animals in deep sea areas—attract prey with light  of the ocean. Therefore, the correct option is C.

What are photophores?

Deep sea animals live in complete darkness where no sunlight can penetrate. In order to find food or mates, many of these animals have evolved special light-producing organs called photophores. These organs emit light, which can be used to attract prey or to communicate with other members of the same species.

The light produced by photophores can vary in color, brightness, and pattern depending on the species. Some animals use their photophores to create a dazzling display that confuses or disorients their predators, while others use them to mimic the appearance of other animals or objects in their environment. Therefore, the correct option is C.

at what point did the climate began to fluctuate more severely ? (2 points )

Answers

Answer:

Due to greenhouse gases.

Explanation:

When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.

Answers

Answer:

Parasitism

Explanation:

Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.

A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.

What are different types of symbiotic associations?

In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.

Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.

In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.

In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.

Hence, the fourth option is the correct answer, which is parasitism.

Plants use carbon dioxide in the atmosphere during photosynthesis, herbivores eat the plants, and a carnivore eats an herbivore.

How carbon move from atmosphere to the biosphere?

Carbondioxide gas move from atmosphere to the biosphere by absorbing by the plants in the process of photosynthesis. These plants are the food of herbivores so they eat it and carbon move from plant to herbivore. Then the carnivore feed on the herbivore.

Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor

Answers

Answer:

La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.

Explanation:

La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).

Choose the mutation that you think has caused Calix’s calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data. ( Ya'll i need a hypothesis )

Answers

The complete question is as follows:

Hypothesis Cas More Information: Here is a summary of the data, Mass of DNA Cat Res per Coll Mother Father Calix 1520 fg 1495 fg 1535 fg . The mass of an X chromosome is 40 fg. • Point mutations do not change the mass of DNA. • In chromosomal rearrangement, some daughter cells gain parts of chromosomes and some lose parts of chromosomes. • In nondisjunction, daughter cells gain a whole entire chromosome. Obe Exp Нур 는 Exp Point Mutation in Melosis Chromosomal Rearrangement Nondisjunction Choose the mutation that you think has caused Calix's calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data.

Answer:

The correct answer is - non-disjunction.

Explanation:

Calix's calico has an X chromosome gene that determines the color of fur. One allele forms orange fur and the other give rise to black. In heterozygous give rise to orange patches on black.

Mother has autosome and 2-X chromosomes.

Mass of 2 X chromosomes will be

= 40*2

= 80fg

So mass of autosomes = 1520-80

= 1440fg

Mass of sex chromosomes in father is = 1495-1440

= 55fg

So the mass of Y=55-40

= 15fg

It is clear that the mass of DNA of Calix is exactly 15 more than DNA of the mother. So we can say that Calix has an entire Y chromosome in extra.

So the answer is non-disjunction.

The right option is - non-disjunction.

Information regarding Calix’s calico:

It comprises of X chromosome gene that measured the fur color. In the case of heterozygous, it provides the increment with respect to orange that patches on black.

Since Mother has autosome and 2-X chromosomes.

So,

Mass of 2 X chromosomes should be

= 40*2

= 80fg

Now

The mass of autosomes should be

= 1520 - 80

= 1440fg

Now

Mass of s-ex chromosomes in father should be

= 1495-1440

= 55fg

Now finally the mass of Y is

= 55 - 40

= 15fg

Based on the above calculation, the mass of DNA of Calix should be 15 i.e. more than the DNA of the mother.
