Two Changes that happen to your gas exchange system when you exercise regularly
Answer:
Hi hope this helps:
During exercise there's an increase in physical activity and muscle cells respire more
The heart rate increases during exercise.
The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
Which statement describes a connection between photosynthesis and cellular respiration?
Question 6 options:
Water is a product of photosynthesis and is a reactant for cellular respiration
Oxygen is a product of both photosynthesis and cellular respiration
Oxygen is a product of photosynthesis and is a reactant for cellular respiration
Water is a product of both photosynthesis and cellular respiration
Answer:
Well i know that is C a reactant. because in order for photosynthesis to take place the plant NEEDS water same with cellular respiration they are in both dier need for oxygen.

15. Which of the following statements is false? A) scientists study rock layers and fossils when developing the geological time scale. B) according to the law of superstition the youngest rock layers are at the bottom. C) The oldest known rocks on earth are approximately 4 million years old. D) earth is constantly changing.
Answer:
B
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)
Hope this helps :)
The statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.
What are the fossils?The fossils are the preserved materials of the animals and plants, such as the skeleton, teeth, bones, imprints, and other parts stored in the different layers of the earth. These fossils are preserved in natural ways, not by humans, and they are helpful for the study of the different animals because some fossils give the idea of the connecting links, and they give the idea of the animals' living conditions in the early time.
Hence, the statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

I’m working on a cell project that is focusing on the nucleus and I have to find a theme song for it. Any suggestions about songs that might relate to the function of a nucleus?
Answer:
https://youtu.be/tRo73dzVfuo
A good song that could serve as a theme song for your cell project is;
The Nucleus Song, sung by Megan and SarahThe song above can serve as a good background for your cell project. It can be gotten from the mainstream video blog under the name Craigdet.
This song is a good choice because its lyrics mention the various parts of the cell, like the ribosomes, endoplasmic reticulum, cytoplasm, etc., and their functions.
It also mentions and displays the nucleus and its role in the cell. The song is educative and entertaining. It will be a good fit for your project.

What is artificial selection? How is the development of different dog breeds an illustration of artificial selection?
Answer:
Artificial selection is process in which humans select the traits in animals and plants and use animal breeding or plant breeding to produce the animal or plants with desired traits.
Different dog breeds is very good example of artificial selection because with the help of artificial selection humans can drastically alter the appearance of dogs. With artificial selection human can develop Great Dane from the tiny Chihuahua.

1pt Place the following steps in the correct order:
1. Sperm nuclear envelope breaks down
2. Genomes blend to form a diploid cell
3. Decondensation occurs
4. Sperm head penetrates egg cytoplasm.
Answer:
The delivery of the paternal genome to the egg is a primary goal of fertilization. In preparation for this step, the nucleus of the developing spermatozoon undergoes extensive morphological and biochemical transformations during spermatogenesis to yield a tightly compacted sperm nucleus. These modifications are essentially reversed during fertilization. As a result, the incorporated sperm nucleus undergoes many steps in the egg cytoplasm as it develops into a male pronucleus. The sperm nucleus (1) loses its nuclear envelope, (2) undergoes nucleoprotein remodeling, (3) decondenses and increases in size, (4) becomes more spherical, (5) acquires a new nuclear envelope, and (6) becomes functionally competent to synthesize DNA and RNA. These changes are coordinate with meiotic processing of the maternal chromatin, and often result in behaviors asynchronous with the maternal chromatin. For example, in eggs fertilized during meiosis, the sperm nucleus decondenses while the maternal chromatin remains condensed. A model is presented that suggests some reasons why this puzzling behavior exists. Defects in any of the processes attending male pronuclear development often result in infertility. New assisted reproductive technologies have been developed that ensure delivery of the sperm nucleus to the egg cytoplasm so that a healthy embryo is produced. An emerging challenge is to further characterize the molecular mechanisms that control sperm nuclear transformations and link these to causes of human infertility. Further understanding of this basic process promises to revolutionize our understanding of the mystery of the beginning of new life.
