Answer:
Everything living would die
Answer:
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.

Answer:
D. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
Explanation:
:)
The answer to this question option A: A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
What this zoologist published tell us of the publishing bias. A research bias is likely to cause wrong results as well as conclusions.
This researcher has incomplete data, this tells us that he made claims that cannot be supported or replicated. Incomplete data makes it difficult to come up with a conclusion.
A publishing bias can happen when there is no significant end result.

Which of the following is most likely to occur as a result of continued high rates of deforestation in the Amazon Básin?
A
The amount of total carbon dioxide in the atmosphere will increase because of decreased photosynthesis.
B
There will be a decrease in soil erosion in the Amazon Basin because of decreased tree cover.
С
There will be an increase in biodiversity in the Amazon Basin community because of decreased competition for habitat.
D
The amount of total water vapor in the atmosphere will increase because of higher rates of transpiration.
Deforestation or forest clearance is the removal of a forest or stand of trees from land. Therefore, option (D) is correct.
What do you mean by deforestation?Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction.
Moreover, the loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.
Therefore, deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities.

Which of the following is true about the Calvin cycle?
a. Rubisco fixes O2 to a carbohydrate molecule.
b. Both ATP and NADPH are needed to make sugars.
c. Light energy is converted to chemical energy.
Answer: Rubisco fixes O2 to a carbohydrate molecule.
Explanation:
Both ATP and NADPH are required to make sugars in Calvin cycle. In the process of Calvin cycle, the atmospheric carbon dioxide is fixed. Thus, the correct option is B.
What is Calvin cycle?
The Calvin cycle is also called the light independent reactions or the dark reaction of photosynthesis. Calvin cycle is also known as the C3 cycle. It is the second stage of the photosynthesis, in which glucose molecules are synthesized. The Calvin cycle makes use of the products formed in the light dependent reaction of photosynthesis such as ATP and NADPH.
ATP and NADPH are the products of light reaction of photosynthesis which are used to synthesize glucose molecule. In the process of Calvin cycle, carbon dioxide (CO₂) is fixed and not oxygen.
Therefore, the correct option is B.

Describe two ways effects on society can impact the decision of whether to mine for resources in certain areas.
In the certain area that people are looking to mine,it may have lots of people. If there a lots of people,and there is an explosion in the mine,lots of deaths would happen. If there was people with lots of sickness,or a huge hospital in the town this would be bad,because they would be spreading possibly toxic and lethal chemicals inside of the town and killing off all of the people. Truly the main reason for society impacting this is health and money. It may be expensive in this area.

There may be a large number of people in the area where people want to mine. There will be many deaths if there are many people and there is an explosion in the mine.
What is mining?Mining is the extraction of useful materials from the earth. Coal, gold, and iron ore are some examples of mined materials. Iron ore is the raw material used to make the metal iron.
Mine exploration, construction, operation, and maintenance may result in land-use change and have negative environmental consequences such as deforestation, deterioration, contamination.
Also, the modification of soil profiles, contamination of local streams and waterways, and an increase in noise and dust.
There could be a large population in the area where people want to mine. If there are a lot of people and there is an explosion in the mine, there will be a lot of deaths.
Thus, this way, effects on society can impact the decision of whether to mine for resources in certain areas.

Gametes are:
O the body cells of an organism
O cells found in prokaryotes
O complex cells found only in plants
O the reproductive cells of an organism
Answer:
the reprodutive cells of an organism
Explanation:
sex cells= gametes
somatic cells=body cells
simple cells (no nucleus)= cells in prokaryotes
Gametes must be haploid because
two gametes will unite during fertilization to create a diploid cell
fertilization results with a haploid zygote
gametes are small and can hold only the haploid number of chromosomes
the gametes' chromosomes will be replicated prior to cell division
Due to the fact that two gametes (one from each parent) unite during fertilization to form a diploid zygote, gametes must be haploid, meaning they contain half as many chromosomes as somatic cells of an organism. Therefore, the correct option is A.
When gametes fuse, a diploid cell with a full set of chromosomes is produced, which combines their haploid sets of chromosomes. After cell division and growth, this diploid zygote will form a new human with a full complement of chromosomes in each cell. To preserve proper ploidy during fertilization and subsequent development, gametes must be haploid.
Therefore, the correct option is A.

17. If the diploid number of chromosomes for an organism is 16, each daughter cell after

One diploid cell produces two diploid cells after mitosis. Therefore, the cell with 16 chromosomes that enters mitosis produces two daughter cells, each with 16 chromosomes. And If the diploid number of chromosomes is 16, each daughter cell after will contain_16_ chromosomes.
------------------------------------------------
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the cell duplicates and then separates.
There are two principal types of cells in the organism that suffer mitosis: Somatic cells and germ cells that are diploid cells (2n). Germ cells are also in charge of gamete production through meiosis.
Both diploid cells (2n) will end their cycle becoming two daughter cells with the same genetic dotation.
A diploid cell that enters mitosis with 16 chromosomes will divide to produce _two_ daughter cells. Each of these daughter cells will have _16_chromosomes.
Each single cell that suffers mitosis, produces two daugther cells. Each of the daughter cells will have the same chromosomic charge as the original cell -in this case, 16 chromosomes-.If the diploid number of chromosomes for an organism is 16, each daughter cell after mitosis will contain_16_ chromosomes.
Diploid number = 2n = 16 chromosomesHaploid number = n = 8 chromosomesEach daughter cell is diploid, meaning that it has 16 chromosomes.------------------------------------------
