Which of the following human actions negatively affect the water cycle by increasing evaporation?

Answers

Answer: Hydroelectricity

Explanation: None Sorry

Burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

Human activity such as the burning of fossil fuels in vehicles and burning of wood for cooking have adverse effect on the earth's atmosphere. This burning of fossil fuels increase the temperature of the earth leads to global warming.

Raising the Earth's temperature means that there is an increase of evaporation, melting of glaciers and sea ice which imbalance the water cycle leads to flood and drowning of coastal regions of the earth so we can conclude that burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

Three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow. One plant grew to have a purple flower while the other two grew white flowers. What is the most likely conclusion that can be made for the change in flower color?(1 point)

Genetic factors caused environmental changes that caused the differences in flower color.

Genetic factors caused the differences in flower color.

Environmental factors caused a genetic mutation that caused the differences in flower color.

Environmental conditions caused the differences in flower color.

Answers

Answer:

The second answer choice.

Explanation:

Genetic variation must be the answer as the plants were grown in the same conditions. Therefore, the only source of variability might be genetic variation.

The first choice is not the answer because Genetic factors cannot cause the environment around the plant to change.

The third choice is not the answer because the Environmental factors are the same, and if they were really to cause a mutation, all three plants would mutate.

The fourth is the same reason as the third: if environemnt conditions affected the flower, all three plants would change color since they were all grown in the same environemnt, not just the one we see in the results.

Some significant floricultural species can now produce flowers with attractive and unique bloom hues thanks to recent advancements in genetic alteration techniques. Thus, option B is correct.

What are the genetic factor in developing organism?

Flower color is governed by two primary gene families. Genes that code for the protein machinery needed to create pigment molecules are part of one category.

The second group includes genes that result in the production of regulatory proteins. The location, quantity, and kind of machinery that makes up the pigments are determined by regulatory proteins.

Flowers have genes that determine how they look, just like humans. These plants “give birth” to pigments, which result in a rainbow of hues.

The carotenoid substance that gives tomatoes and carrots their color also gives some flowers their yellow, red, or orange hue.

Therefore, Genetic factors caused the differences in flower color.

Do you believe in the sanctity of life? Why/ why not?

Answers

Answer:

Yes

Explanation:

Part of religion

Yes. Because I am an emotional being with a life that I value. What happens to my perceptual and emotional being upon the end of my life is unknowable. I possess empathy and a subsumed theory of mind. I can project my own emotions and desires onto those of other beings. I therefore assume that all emotional beings value their own life as I do my own. Out of my empathy for others and my desire that others will empathize with me, I can value the lives of other emotional beings on their behalf. Because it is impossible to know with any certainty what of my emotional being will survive end of life, I place a very high. Perhaps the highest value on my life and by extension the lives of others. To me it seems that spiritual belief precepts which undermine the singular uniqueness of this life experience through afterlife or reincarnation mythologies those can only undermine and lessen the value i.e. the sanctity of life.

They have unique combinations of chromosomes.

What are gametes?

In organisms that reproduce sexually, a gamete is a haploid cell that unites with another haploid cell during fertilization Gametes, commonly known as sex cells, are an organism's reproductive cells.

A female is any individual that generates the bigger kind of gamete—called an ovum—and a male creates the smaller type—called a sperm—in species that produce two morphologically distinct forms of gametes, and in which each individual produces only one type.

The flagellum, a tail-shaped feature that enables the cell to propel and move, is what makes sperm cells, or spermatozoa, tiny and motile. On the other hand, each egg cell or ovum is sizable and non-motile.

Therefore, They have unique combinations of chromosomes.

When a cross between 2 contrasting parents produces a new phenotype, it is known as incomplete dominance. In diploid (2n) organisms, individuals receive one allele or gene variant from each parent.

Heterozygous individuals carry different alleles for the same gene locus.

Incomplete dominance occurs when both alleles are expressed in heterozygous organisms.

A positive feedback mechanism is a technique of the body in which the body works or secretes something to the body that is needed more in the body, and it is secreted in the body out of league and number.

Platelets are present in the blood. They are spherical and are colorless and small. They help in blood clotting when there is a cut or bleeding, it prevents loss of blood by clotting the blood.

The most likely conclusion that can be made for the change in flower color is that genetic factors caused the differences in flower color.

According to this question, three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow.

However, despite the uniformity in the environmental conditions received by each plant, one plant grew to have a purple flower while the other two grew white flowers.

This difference in flower color is likely caused by the inherent genetic factors of each plant rather than environmental factors because they were treated the same.

Temperature-sensitive alleles are an example of conditional alleles; at the permissive temperature, the gene has normal function, whereas at the restrictive temperature, the gene has mutant function. You are studying the E2F pathway and you obtain a temperature-sensitive CDK4 mutant. At the permissive temperature, CDK4 functions normally. At the restrictive temperature, CDK4 is non-functional. Would you expect cells to continue growing or stop dividing when at the restrictive temperature? Explain your answer.

Answers

When at the restrictive temperature, we can comfortably expect the cell to stop dividing, whilst continuing to grow

The E2F pathway in a cell is responsible for the transition from the G1 stage of the cell cycle to the S stage. The G1 stage is where a cell grows and expands before the duplication of its DNA.

The S stage stands for synthesis. This is the moment in the cellular cycle in which the DNA of the cell is copied in order to prepare for cellular division.

Therefore, if the transition from G1 to S is blocked by temperature restrictions, we can expect the cell to continue growing, but not divide.

Appearance*In most frog species, the female is larger than the male, so frog size relative to a standard can be a good method of gender identification. In some species, the female frog is darker in color than the male, and in others, the male is darker.

Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them.In this case, the eggs are fertilized inside the female's body before they are released.
