Explanation:
Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

Answer:
answer is in explanation before
Explanation:
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. Overgrazing combined with overstocking has the most damaging outcomes to the world’s natural environment. The scarcity of water resources, water pollution, degeneration of coral reefs, and eutrophication are all connected to overgrazing. The chief polluting elements include farm chemicals and animal wastes.
Types of grazing systems 1. Types of grazing systems Grazing animals (such as cattle, sheep and goats) feed on the leaves and shoots of grass... 2. Zerograzing In this type of grazing system, the animals are not allowed to go out into the pastureto graze.
Overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
What is overgrazing?There are three types of grazing systems: continuous grazing, rotational grazing, and intensive grazing. Continuous grazing involves leaving livestock on a particular area of land throughout the year. Rotational grazing involves rotating livestock to different areas of land to prevent overgrazing. Intensive grazing involves keeping livestock in smaller paddocks and rotating them frequently.
Hence, overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.

Explanation:
Bacteria are only able to be produced from other bacteria already existing on earth.
Which theory best describes this?
Answer:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Bacteria do not grow and multiply the same way as animals or humans. They take in nutrients and reproduce by dividing – one bacteria splits and becomes two bacteria, two become four, four become eight and so on.

Which of the following best predicts and justifies how the proportion of the Tibetan population with big blood vessels living in the mountains will change over the next 1,000 years (assuming conditions remain stable)?
Question 2 options:
I predict that the proportion of individuals with big blood vessels living in the mountains will decrease because there is a variation in blood vessel size and those with the smaller blood vessels can store more red blood cells than larger vessels, so more oxygen can be moved to the body cells. Therefore, they have a better chance of surviving and passing this trait on to their offspring.
I predict that the proportion of individuals with big blood vessels living in the mountains will stay the same because there is a variation in blood vessel size and that variation will remain in a population. The is what is so cool about humans, we are all so unique.
I predict that the proportion of individuals with big blood vessels living in the mountains will increase because there is a variation in blood vessel size and those with the bigger blood vessels can deliver more oxygen to the body cells and therefore have a better chance of surviving and passing this trait on to their offspring.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.
Answer:
Over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the number of red blood cells it makes, not its blood vessels.
Explanation:

Answer:
Low cost has low quality whereas high cost has high quality.
Explanation:
If the main criterion was keeping the cost of materials as low as possible so he must used the materials of low quality for their work because the low quality materials are made of cheap material while on the other hand, if the main criterion was getting the best performance from the material so he has to used the materials of high quality. The high quality materials are very expensive but its performance is excellent as compared to cheap materials.

Identify how information for specifying the traits of an organism is carried in the DNA.
Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.
What is a gene?Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.
This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.
Hence, the information for specifying the traits is carried by genes present in DNA.

explain why aerobic respiration occurs before lactic acid fermentation in most muscles.
Aerobic respiration occurs when there is insufficient oxygen is present in respiration. If the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration.
Aerobic respiration:Aerobic respiration occurs in the cell of the body.It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food.Water and carbon dioxide are produced as end products.Thus, we can conclude that aerobic respiration occurs when there is insufficient oxygen present for respiration. if the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration. The acid wears away muscles and causes cramps.

The bone cell of a goat contains 60 chromosomes.How many chromosomes will be in each daughter cell after mitosis
The bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.
What exactly is mitotic cell division?The cell divides during mitosis, and the daughter cells formed have the same genetic content as the parents, here, two daughter cells are formed, with the bone cell having genetic content same as original bone cell. Because the duplicated chromosomes are separated equally by the spindle fibers without crossing over or recombination, 60 chromosomes will form that is the same number of chromosomes after mitosis.
Hence, the bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.

Answer:
16. Directional Selection
17. Disruptive Selection
18. Stabilizing Selection
19. Natural Selection
20. Adaptation
Explanation:
In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.
Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.
Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.

WILLL GIVE BRAINLIST!!! Suppose mechanical weathering breaks a rock into pieces. How would this affect the rate at which the rock weathers chemically? How do chemical and physical weathering differ? Explain your answer in at least 3 sentences.
Answer:
Explanation:
Mechanical weathering increases the rate of chemical weathering.
As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.
Chemical weathering is different from mechanical weathering(physical weathering ) because the rock changes, not just in size of pieces, but in composition.
That is, one type of mineral changes into a different mineral.
Chemical weathering works through chemical reactions that cause changes in the minerals.
