Answer:
birthrate
Explanation:
In a density-dependent population, an increase in birthrate will most likely lead to an increase in population density. So, the correct option is A.
What is population density?Population density is the number of people in a given area of land. It primarily applies to people, yet occasionally it also does to other living things. That is a crucial geographic phrase. The amount of people who live in an area per square kilometer, or even other unit of land area, is referred to as population density.
We must divide the population's number by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area. Square miles or square kilometers should be used as the measure of land area. If we need to calculate the density of a relatively small place, then can use square feet or meters.
Therefore, the correct option is A.

which type of traits are responsible for evolution?
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

After fertilisation of plants
occurs between the male gamete and the egg cell, the zygote produced undergoes mitosis forming two cells. explain.
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.
Explanation:
Fertilization is defined as the fusion of the male gamete (sperm) and the female gamete (egg cell) in plants that develops into a zygote. After fertilization, a series of events occurs in the zygote to develop into a seed.

state two functions of the onjective lens on a microscope
Answer:
please give me brainlist and follow
Explanation:
In microscopy, the objective lenses are the optical elements closest to the specimen. The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens. Objective lenses are the most complex part of the microscope due to their multi-element design.

5. Non-point source
It is mainly caused by
1. Industrial waste
2. Oils leak and spills
3. Global warming
4. Agriculture
It can be controlled by not using chemical fertilizers in the agricultural field, use the minimum amount of detergents or bleach near water bodies.

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the
male minnows all had a moderate number of spots
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were
better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female
minnows in this pond preferred to mate with males that had the most spots,
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
Answer:
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.

In the Galapagos Islands, there were many species of tortoises, woodpeckers and other animals. Why were the animals like the tortoises so different in appearances, when they lived on neighbor islands?
Answer:
The animals were different because there were things the animals need to adapt to in the Galapagos that may have changed their appearance. for example a bird may have a different shaped beak because they started to evolve so they could eat foods that were available to them on the island

~Pinky~
Answer: I do know the answer, I always use the Study Guide, which is incredibly helpful, I will share both my notes, and answer, which is D. Trees begin to grow in thick, rich soil.
Explanation: After a volcanic eruption, a process known as a Ecological Succession happens. Resulting in, lichens, which is the first living species to grow on the rocks. Afterwards, mosses and small annual plants are the second species, these species begin to grow in soil made by the lichens, since after the eruption the lichens release acid that helps break the rock into soil, then the mosses and annual plants reproduce by the help of the wind, and use the soil formed by the previous species. Furthermore, grasses and other long living plants begin to grow in the richer soil. Then, grasses, shrubs, and intolerance trees, such as pine form. Until, the last observed, which is shade-tolerant trees, such as oak and hickory! Have a good day, you’re welcome. P.s. Provided a picture from my source!
