Answer:
camoflauge and predation, say that a bird likes to eat a species of insects. some of the insects are green and others are black. since the bird will easily spot the black ones first against a green leaf, the black insect population will die out, and only green insects get to reproduce and in turn only produce green insects. this decreases the frequency of genes that make them black

What is the force of attraction objects have due to their mass
1. According to Model 1, in what type of organs are the cells that enter meiosis I found? 2. Considering what you already know about mitosis in cells, what event must take place during interphase before a cell proceeds to division? 3. What two structures make up a single replicated chromosome? 4. In Model 1, how many replicated chromosomes does the cell contain during prophase? 5. At which stage in meiosis I do the pairs of homologous chromosomes come together? 6. Once the chromosomes have formed a pair, what are they called?
Answer:
1.) Sex organs
2.) DNA replication
3.) Sister chromatids
4.) Two identical daughter cells
5.) Late prophase 1
6.) Tetrads
Explanation:
Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.
Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.
Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS
PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.
Once the chromosomes have formed a pair they are called TETRADS

Viruses take over a host cell to carry out reproduction. In which way do viruses use the cell's parts for reproduction?
Answers:
The viruses use the cell's organelles to replicate its viral genome.
The viruses use the cell's genetic material to replicate its viral genome.
The viruses use the cell's organelles to replicate its host's genome.
The viruses use the cell's genetic material to replicate its host's genome.
Answer:
The virus uses the cell's genetic material to replicate its viral genome
Explanation:
During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material within hence further during the uncoating and replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.

Please help with questions 2-5. Will mark branliest!!
Answer: 2. C
3. D
4. D
5. B
Explanation:
2. All living things are made up of MULTIPLE cells, even the smallest creature has multiple cells, the cells are just smaller so that they all fit into that one creature. So the answer is that C: "Some living things are made up of only one cell", because all living things are made up of many, many cells
3. It would be Tissues, what gave it away would be that, not only is Q a long strip, which takes out Bacteria and Muscles, but then S takes out Root's which leaves Tissues. The answer is D: "Tissues", because the Q and S cross out all other answers
4. Their root system is the tissues, which work the most in plants, their tissues also help with eating, breathing, and even standing upright. The answer is D: "Tissues", it works the most for a lot of reasons
5. Connective, Muscular, Nervous, and Epithelial (which is not a part of the question) are all human tissues, so Meristem is not a human tissue, in fact, its a PLANT tissue, also known as Meristematic Cells. The answer is B: "Meristem", because it is a plant cell, not human.

The main difference between the four nucleotides that make up DNA is that they have differentRequired to answer. Single choice.
Answer:
bases.
Explanation:
Nucleotides are the basic building blocks that make up DNA, consisting of a deoxyribose sugar, phosphate group, and nitrogenous base. The main difference between the four nucleotides is the nitrogenous base, Adenine, Thymine, Guanine, or Cytosine. Adenine pairs with Thymine, and Guanine pairs with Cytosine. The order in which these pairs come in code for proteins and hold genetic information.

How do absorption, reflection, and refraction change the movement of P waves?
Answer:
Absorption, reflection and refraction will all change of the movement of P waves. Absorption will reduce the energy of the waves. Reflection will bounce the waves back. Refraction will change the angle of the waves based on what they are bouncing off of.

PLEASE ANSWER!!!!! I need an explanation please!!!! how can plants reduce carbon emissions using photosynthesis?
Answer:
Plants convert carbon dioxide and water into sugar and oxygen through the process of photosynthesis. Plants absorb carbon dioxide from the atmosphere during photosynthesis. A small amount of carbon dioxide is released during leaf respiration (intake of oxygen), but it is quickly re-absorbed during photosynthesis.
