Natural selection causes changes in? A.genotypes. B.populations. C.individuals. D.phenotypes.
Answer:
populations
Explanation:
A) genotypes
Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.
Recall that genotype is the type of alleles one has.
B) populations
Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.
C) individuals
Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.
D) phenotypes
Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.
Recall that phenotype is the physical appearance one has.
Extra:
Phenotype vs. Genotype:
If A is dominant for brown hair and a is recessive for albino hair:
Genotype Aa has a phenotype of brown hair.
Genotype AA has the phenotype of brown hair.
Genotype aa has the phenotype of albino hair.
You can see how genotype and phenotype are like.
Natural selection causes changes in populations. The correct option is B.
What is natural selection?Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.
Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.
A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.
Therefore, the correct option is B.

Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule synthesized by plants using that product
Answer:
(A) nitrates—proteins
Note: The question is not complete. The complete question is given below:
Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule
synthesized by plants using that product?
(A) nitrates—proteins
(B) ammonia—carbohydrates
(C) nitrogenous wastes—nitrites
(D) atmospheric nitrogen—nitrates
(E) atmospheric nitrogen—ammonia
Explanation:
The nitrogen cycle refers to the cycle through which nitrogen is transferred for use through both living and non-living things, involving the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is especially important for living things because nitrogen is essential for the formation of amino acids which form proteins.
The nitrogen cycle occurs in five stages:
1. Nitrogen fixation - Nitrogen gas from the air is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds.
2. Nitrification - Ammonia is converted to nitrates by nitrifying bacteria in the soil.
3. Assimilation - Plants absorb nitrates from the soil and use them to make proteins. The plant is then eaten by an animal and are used to produce animal protein.
4. Ammonification- Decomposers break down the bodies of dead organisms, urine and faeces converting them to ammonia in the soil, which is then converted to nitrates by nitrifying bacteria.
5. Denitrification - Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air.
From the above stages and the options provided, the correct option is A - nitrates from the nitrogen cycle is converted to protein by plants.

seeds
stems
(pls don’t guess or leave links)
Answer:I would say seeds, since it protects the bud of a flower and then the flower “hatches” from the seed and grows
Explanation:
The plant structure that is similar in functions to eggs is seeds. The correct option is C.
What are seeds?A seed is an embryonic plant with a protective outer covering and a food reserve. The formation of the seed is a part of the reproduction process in seed plants, including gymnosperm and angiosperm plants.
Similarly, an egg is an oval or round object laid by a female bird, reptile, fish, or invertebrate that typically contains a developing embryo.
Bird eggs are protected by a chalky shell, whereas reptile eggs are protected by a leathery membrane.
Embryos are developing in seeds and eggs. Both provide food for the developing embryo. Both have protective coverings that keep them from drying out.
Thus, it can be concluded that the correct option is C.

The two specific concerns of species diversity are species survival and evenness of species abundance. The correct options are A and B.
What is species diversity?"Species diversity is defined as the number of different species present in an ecosystem and their relative abundance." When all of the species present are equally abundant in the area, diversity is greatest.
Species diversity is a measure of the number of different species found in a given ecosystem or habitat.
It is critical to be concerned about species survival because the extinction of a species can have a negative impact on the entire ecosystem.
Furthermore, the evenness of species abundance is important to consider because the dominance of one or a few species can have a negative impact on the diversity and stability of an ecosystem.

Polar bears live in the tundra. They obtain their energy almost exclusively from eating other animals, although they do eat some vegetation. Black bears that live in temperate forests tend to be more omnivorous, eating a wide variety of plants and animals for energy.
An adaptation is a behavior or an anatomical structure that can help an organism survive in its environment. Why are diet choices important adaptations for these animals’ survival in their biomes? Based on the images, what other adaptations do these animals display?
Answer:
In the tundra, vegetation is rare, so polar bears had to adapt to eat a heavily animal-based diet. In the temperate forest region, a wider variety of plants is available, so black bears can eat a more omnivorous diet. The bears’ colors are adaptations. The polar bear blends in with the snowy background, and the black bear blends in with the trees of the temperate background. The bears’ coloring could help them hunt for prey.

Do the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell?
Answer:
Yes.
Explanation:
Yes, the positive charges on both calcium ions and sodium ions will responsible for the movement of these ions into or out of the cell because the membrane has negative charge which attract these positively charged calcium ions and potassium ions. These difference concentrations of sodium and potassium in the cell are due to the activity of cell membrane active transport system which moves sodium out of the cell and potassium into it.
Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.
What do you mean by Diffusion?Diffusion may be defined as a process resulting from the random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
The membrane of a cell possesses a negative charge, so it attracts these positive charge ions and makes a concentration difference that leads to the process of active transport through which sodium moves out of the cell and potassium into it.
Therefore, Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.

Answer:
Stalactites form on the ceiling when water seeps through the ceiling and deposits calcite. Eventually a soda straw develops, which develops into a stalactite after many more depositions of calcite.
Stalagmites form when calcite-rich water falls to the floor from the ceiling, splattering minute amounts of calcite on the floor. After many such depositions, a stalagmite begins to take shape.
Explanation:
In general, we can say that stalactites form on the ceiling of a cave and grow towards the floor, while stalagmites form on the floor and grow towards the ceiling.
More fully, we can say that a stalactite forms when a quantity of water rich in calcite flows through the fissures of a rocky soil and infiltrates the roof of a cave where it also flows, due to the action of gravity. However, this drop of water and calcite does not fall on the cave floor and gets stuck in the ceiling. Over time, the water in this drop will evaporate, but the calcite will sediment in the shape of a ring, still attached to the cave ceiling. This process is repeated countless times, until a hollow calcite tube, called straw, is created. Over time this Straw will start to accumulate sediment and will clog. This promotes a modification of its shape, which changes from a tube to an inverted cone, with a point facing the cave floor. At that point the stalactite is formed.
Stalagmite occurs when the drop of water and calcite falls on the floor of the cave and likewise, the water in the drop will evaporate and the calcite will settle. The more drops that undergo this same process, the calcite sediments accumulate, but this time, they will not form a hollow tube, but a solid tube. This is how stalagmite is formed.
The formation of stalactites and stalagmite lasts for many years and when a stalactite meets a stalagmite, it can form a single structure, called a column.
The calcium rich water gets deposited on the roof and also get deposited on the floor of the caves. This calcite deposition form ring like structures.
The correct answer is:
Stalactites form on the roof when water flows through the roof and sediments calcite. Eventually, a soda straw forms, that grows into a stalactite after many more accumulations of calcite.Stalagmites form when calcite-rich water falls on the ground from the roof, dispersing little amount of calcite on the ground. After many such depositions, a stalagmite starts to take shape.This can be explained as:
Stalactite grows on the ceiling towards the floor while the stalagmite form on the floor and form the structure in an upwards direction.When the roof caves get infiltrated by the calcium-rich water the stalactite is formed.The calcite water gets accumulated over and over and a ring is formed.This tubular structure is called straw.When the calcite water drops on the floor of the cave then the water will evaporate leaving the calcite behind.Over time, this calcite will sediment and will form a solid structure.Therefore, this is how stalagmite and stalactite are formed.
