The statement which is true about Genetic drift is that it can decrease genetic diversity in a population. Thus, the correct option for this question is A.
What is Genetic drift?Genetic drift may be defined as a type of evolutionary force that significantly involves the mechanism of evolution in which the allele frequency of a population may change over generations due to chance or sampling error.
The process of genetic drift occurs in all populations of non-finite size but its effects are strongest in the smallest populations. It is considered an assumption under the Hardy-Weinberg equilibrium. So, option C is eliminated.
The concept of the founder effect and genetic bottleneck always decreases the genetic diversity among the population. So, option D is eliminated.
Therefore, it can decrease genetic diversity in a population is that statement that is true about Genetic drift. Thus, the correct option for this question is A.

Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others, they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting behavior of bats be affected by such an environment?
A.
Bats would be better able to use echolocation, which would improve their ability to find prey.
B.
Bats would be unable to use echolocation, which would prevent them from finding any prey.
C.
Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase.
D.
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.

How do human activities lead to primary succession?
Answer:
This succession is influenced by environmental factors such as soil type, water regimes, vegetation history, climate, and invasive species. Humans affect all of these factors. The human dimension introduces the greatest amount of unknown variability. Forest lands are under increasing development pressure.

Describe two processes of weathering and two processes of erosion that are taking place in Sam's backyard.
es
Answer and Explanation:
When viewing the image of Sam's backyard, we can see the occurrence of chemical and physical weathering. Physical weathering is caused by the impact of water on rocks, which promotes the breakdown of rock particles. The chemical weathering is also caused by the water that I contact with the rock react with its elements causing chemical reactions that modify the rock.
Regarding erosion, we can consider the erosion by gravity that is common in mountainous regions, like the one shown in the photo. This type of erosion promotes the loss of mass of the rock due to the detachment and rolling of rock particles, due to gravity. We can also notice the rain erosion, created by the impact of water on the rock that detaches the fragments and transports them to other places.

Answer:
Fallopian tube
Explanation: A pregnancy starts with fertilization, when a woman's egg joins with a man's sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
