Imagine a disease that kills 50% of the male roaches i a population. do you think this would affect birth rate? briefly explain. 3. if a disease instead killed 50% of females, would it likely affect birth rate? briefly explain.

Answers

Answer 1

Answer:Part 1.

If 50% of males in a population dies then the birth rate will decrease to 50%.

Explanation:

For example in a population there are 100 males and birth rate is also 100 per year.

Then after disease only 50 males will remain to reproduce and 50 babies will birth in a year. Hence birth rate also decreased by 50%.

Part 2.

If 50% of females in a population dies then the birth rate will decrease to 50%.

Explanation:

For example in a population there are 100 females and birth rate is also 100 per year.

Then after disease only 50 females will remain to reproduce and they will give birth to 50 babies in a year.

Hence birth rate also decreased by 50%.

Answer 2

Yes, the death of both male and female affected the birth rate of the roaches.

Both male and female death affected the birth rate of roaches because male and female are required for the increasing and maintaining birth rate. Male mate with female produces offspring so male as well as female are necessary for the birth of baby roaches.

If male population becomes half or 50% so due to less mating less female produce less baby roaches which results in decrease of birth rate while on the other hand, if the female population reduced to 50 % then less females are available for producing baby roaches which also affect the birth rate so we can conclude that the death of both male and female affect the birth rate of the roaches.

How can recycling materials lead to environmental sustainability?

Answers

Answer: Recycling materials helps decrease the amount of new materials taken from the environment.

Happy to help! :) Maybe brainliest plz?

Recycling materials can contribute to environmental sustainability by conserving resources, reducing energy consumption, minimizing waste, and preventing pollution.

Through recycling, we can conserve natural resources like timber, minerals, and oil, as recycled materials can be used as alternatives to these resources.

Recycling also requires less energy compared to producing new materials, resulting in reduced greenhouse gas emissions and a smaller carbon footprint.

By diverting waste from landfills, recycling helps minimize pollution, protect ecosystems, and preserve valuable landfill space.

It promotes a circular economy, where materials are reused and recycled, reducing the need for resource extraction and contributing to long-term environmental sustainability.

C on Edge

Explanation:

YW ;)

Final answer:

b) Increased water quality is not a direct benefit of carbon sequestration in soil, while decreased erosion, increased water storage, and increased soil quality are.

Explanation:

The options given are concerned with soil improvement through carbon sequestration, including decreased erosion, increased water quality, increased water storage, and increased soil quality.

Each option provided, except for increased water quality, is a direct benefit of carbon sequestration in soils. While soil carbon sequestration can improve soil stability, moisture, and organic matter content, thereby reducing erosion, increasing water storage, and enhancing soil quality, increased water quality is a byproduct of these benefits rather than a direct effect of carbon sequestration in soil. Therefore, increased water quality (b) is the answer that does not directly represent a benefit of carbon sequestration on soil.

How could UV light potentially affect an organism’s trait

Answers

UV light could change the DNA of the skin cells of the organism, possibly causing cancer cells to form.

UV light can affect the traits of organisms by changing their DNA sequence.

The DNA of organisms store the genetic information which is physically expressed as traits during gene expressions.

Also, the nucleotide sequence of DNA determines the kind of traits that will be expressed.

UV light has the capacity to alter the nucleotide sequence of DNAs, a phenomenon known as mutation.

When the DNA sequence is altered, the traits originally expressed by the DNA also become altered.

A space probe discovers a planet inhabited by creatures that reproduce with the same hereditary patterns seen in humans. three of the phenotypic characteristics of these creatures are: height, antennae, and nose morphology. earth scientists were able to do some controlled breeding experiments with these organisms. 100 males and 100 females were used in the experiments and the results of a number of crosses are shown below. review this information and use it answer the questions that follow.

Answers

To determine the recombination frequency for controlling the tallness and antennae is 46 tall with antennae, and this results to 46 percent. The expected were 42 dwarfs with no antennae and resulted to forty-two percent. The expected seven dwarf with antennae is seven percent.
When there is recombinant the five tall with no antennae are five percent, then the recombinant total to one hundred. Then the recombination frequency which is between genes A and T is twelve percent. If we determine the recombination frequency for the genes which control snout and antennae is forty-seven antennae with upturned snout which results to forty-seven percent. The expected forty eight no antennae with downturned snout resulted to forty-eight percent. The expected two antennae with downturned snout resulted to two percent. When the recombination of the three no antennae with upturned snout resulted in three percent, then the recombination for genes S and A is five percent

Final answer:

The biological analysis of the alien creatures reveals that they follow hereditary patterns similar to humans, with both genetic and environmental factors influencing changes in their phenotypic characteristics. Traits passed on from parent to offspring can vary, creating an evolutionary pattern of 'descent with modification', while environmental conditions can also influence these traits.

Explanation:

The subject of this student's question is within the field of Biology, specifically focusing on the themes of genetics and evolution. The information provided points towards understanding how different phenotypic characteristics (height, antennae, and nose morphology) observed in these alien creatures follow hereditary patterns similar to those in humans.

Firstly, it's important to note that most characteristics of organisms are inherited, leading to offspring sharing similar traits to their parents. However, offspring also vary in their characteristics. This variance is due to the genetic makeup of the organism, and significant changes in the genetic makeup can lead to a new trait becoming prevalent. This cycle repeats in what scientists describe as 'descent with modification'. Morphological and genetic similarities seen in this phenomenon are referred to as homologous structures.

It's also important to consider the influence of environmental factors which can cause alterations in phenotypes. For example, sun exposure can affect skin pigmentation, and for some species, their sex is even determined by the environment through a process known as temperature-dependent sex determination.

He hormone oxytocin suppresses energy metabolism during pregnancy. reduces the ability of blood to clot during the birth process. increases a woman's appetite during pregnancy. enables the "let-down" reflex to occur when a woman breastfeeds her baby.

The hormone oxytocin enables the "let-down" reflex to occur when a woman breastfeeds her baby.

A student observes poor growth of plants in a garden containing high clay content. Clay content reduces drainage in soil. Which of these is the best method to improve plant growth in the garden?

Answers

add more sand to the soil

If your garden soil has a lot of clay in it, you should add some sand. Use the right kind of sand, mix it in at a 1:1 ratio, and add enough organic matter.

What is sand soil?

Sand added improperly to clay soil can result in a concrete-like material that is unfit for plant growth.

Sandy soil loses moisture rapidly, resulting in limited water retention that is inappropriate for plant development. Water logging results from clay soil's excessive water retention.

A potting mix gets more air space from the sand. It is better to use coarse or building sand. Avoid using plaster and fine sand since they produce a thick mixture.

Therefore, sand is a fantastic choice for plants that are top-heavy and may topple over since it is heavier than other components.

First we must understand why the temperature changes, as earth rotates parts of it get closer to the sun like a globe the earth is tilted which makes part of the earth closer to the sun than other parts.
