Write an explanation based on natural selection for the high incidence of tusklessness among female elephants in Gorongosa. Like all good scientific explanations, your explanation should include a claim, supporting evidence, and scientific reasoning to link the evidence to the claim. Use the Scientific Explanation of Evolution by Natural Selection chart
Answers
Answer:
Argument: A trend toward an increased incidence of tusklessness will result in decreased population sizes in the
future.
Claim: In the long term, tusklessness in African elephants is not beneficial to populations, even when heavy
poaching is occurring. So, as tusklessness increases, elephant population sizes will decline.
Evidence: Although poachers kill elephants with tusks, elephants rely on their tusks for survival. Elephants use
their tusks to strip bark off trees for food and to dig up water and minerals from the ground. Male elephants
also use their tusks in competitions with other males for females.
Reasoning: Tuskless elephants are probably not as healthy as those with tusks, as they cannot eat bark off trees
and are unable to dig for water and minerals. During harsh conditions such as droughts, elephants without
tusks would be less likely to survive. Male elephants without tusks are also more likely to be injured during
mating competitions. If too many males are injured or killed, there may be a decline in reproduction.
Over time, many of the tuskless elephants will die or be unable to reproduce, so the population’s size will
decrease.

What type of carbon cycling occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas?
long-term carbon cycling
carbon storage cycling
carbon release cycling
short-term carbon cycling
Answers
Answer:
The type of carbon cycling that occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas is called the geological carbon cycle. This cycle involves the long-term storage of carbon in rocks and fossil fuels like oil, coal, and natural gas. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels.
Explanation:
The carbon cycle can be divided into two main categories: the short-term carbon cycle and the long-term carbon cycle. The short-term carbon cycle involves processes that cycle carbon through the Earth system on roughly annual/decadal timescales. This includes photosynthesis, respiration, and decomposition of organic matter. The long-term carbon cycle takes millions of years to come full circle and involves the movement of carbon between rocks, soil, ocean, and atmosphere through a series of chemical reactions and tectonic activity. Carbon is stored in rocks and fossil fuels like coal, oil, and natural gas for a long time in the geological carbon cycle. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels in both short-term and long-term cycles
What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Answers
Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

A pedigree chart is used to _______.

predict genotypic probabilities
track inherited traits through generations

Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
Answers
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.
