Answer:

Hey! Neko here!

Explanation:

That new empty space inside the leaves creates a low pressure, and like a drinking straw, this low pressure allows water below the leaf to travel up the stem. You’ll see the little tubes the water travels up when you cut the celery stem, and you can see the colour up in the leaves.

hope this helps ig! <3

We cut the celery stem under water to see the color change in the stem due to movement of water through the process of transpiration in the cell.

Celery stalks or stems are the petioles of the compound leaves. They are not the stems, in spite of the widespread misrepresentation in elementary school lesson plans only. They may also look like the stems to some people because they are thick and fleshy due to accumulation and have prominent veins which are running lengthwise through them.

When we cut the little tubes or celery stem under water travels up when and we can see the color up in the leaves. This process is called as transpiration. The new empty space which is present inside the leaves creates a low pressure, and just like a drinking straw, this low pressure allows the water below the leaf to travel up the stem.

Explanation:

The patterns of background radiation are information that astronomers use to calculate the age of the universe. Therefore, the correct statement is option D.

Big Bang theory gives evidence about cosmic microwave background radiation that filled the early universe. The CMB radiation has uniformity in all directions, but it has slight temperature variations.

These variations are the result of small fluctuations in the density of matter in the early universe, which results in the formation of galaxies and other structures.

The patterns of these temperature variations are studied and astronomers learn about the properties of the early universe to make calculations about the age. They can use CMB radiation for estimation of the amount of time passed since the universe began expanding rapidly in the aftermath of the Big Bang.

Therefore, the patterns of background radiation provide very important information from which astronomers can calculate the age of the universe which is estimated to be about 13.8 billion years old.

I'm in high school Aquatics and I had this question popped up

Answer: C.

Explanation:

Slaves did not have any rights

The statements about African slaves in America are true: they had no rights under the law, which is option C, as the African slaves in America were denied basic human rights and were treated as property rather than as human beings.

The enslavement of Africans in America is a dark and painful chapter in the history of the United States. Beginning in the early 17th century, millions of Africans were forcibly brought to America and sold into slavery, where they were subjected to a lifetime of bondage, exploitation, and abuse. Under the system of slavery that existed in America, slaves had no legal rights and were not recognized as human beings under the law.

Hence, the statements about African slaves in America are true because they had no rights under the law, which is option C.

Random sampling and mark and recapture methods are both commonly used to estimate population sizes, but they have different strengths and weaknesses.

Random sampling involves selecting a random sample of individuals from a population and using that sample to make inferences about the population as a whole. This method is typically used when the population is large and diverse, and it is difficult to observe or count all individuals. Random sampling is also useful when the population is not easily marked or tagged, as it does not rely on the use of markers.

On the other hand, mark and recapture methods involve marking a subset of individuals in a population, then releasing them back into the population and later re-capturing them. The number of marked individuals that are recaptured is used to estimate the population size. This method is typically used when the population is small, and it is relatively easy to observe or count all individuals. Mark and recapture methods are also useful when the population is easily marked or tagged, such as with fish or birds.

A situation in which random sampling would work best is a study of the population of deer in a large forest. The forest is too vast to observe or count all individuals, so a random sample of deer would be selected and observed to estimate the population size.

On the other hand, a situation in which mark and recapture methods would work best is a study of the population of fish in a small lake.

Producers are organisms that create food from inorganic matter. The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates. Consumers are organisms that cannot create their food. I think hehe

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Explanation:

This is because a bad ratio would be one where the volume is larger than the surface area. Once a cell's volume is larger than the surface area, there's not enough surface area to process all the products coming in and waste coming out. Ideally, you'd want a surface area and volume to be as close to each other as possible in number, but you'd rather have the volume be less than the surface area.

After pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.

Ecological succession may be defined as the gradual and continuous replacement of one species by another over a specific period of time.

After the primary succession occurs, the pioneer species are evolved, and due to this, the process of ecological succession carries forward. These pioneer species are generally plants that performed photosynthesis.

Therefore, after pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.

Explanation:

more objects and closer. We can also look at more distant points in space

When we look at the same portion of the sky with an even more powerful telescope that is in space then we will be able to see faraway objects. James Webb Space Telescope is the most powerful telescope.

A telescope is a device used to observe the distant objects present in space by the emission, absorption, and reflection of electromagnetic radiations.

The James Webb Space Telescope is also known as JWST or Webb telescope, which is NASA's largest and most powerful space science telescope till date. The Webb telescope is able to observe the planets at or beyond the orbit of Mars, satellites, asteroids, and Kuiper belt objects.

Many important molecules such as ice, and minerals have the strong characteristic signature at the different wavelengths Webb telescope can observe the objects. Webb telescope can also monitor the weather of planets and their moons.

Answer: Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 96.

Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFB genotype is 12.

The population may be evolving because the actual number of individuals with each genotype differs from the expected number of individuals with each genotype.

The population is not at Hardy-Weinberg equilibrium.

Explanation:

The FB allele should accounts for 120 of the alleles (40 × 2 = 80 in FBFB wolves, + 40 × 1 = 40 in FBFW wolves).

the FB allele would make up 20% (120/600) of the total alleles in the population, so the value of p would be 0.2. The allele frequencies of the population must add up to one for it to be valid (what this means is p+q=1); therefore, since the value of p is 0.2, and the value of q is 0.8.

According to the Hardy-Weinberg equation, the expected frequencies of the genotypes would add up to 1.

= p2+2pq+q2

= 1

or

= 0.22+2(0.2)(0.8)+0.82

= 1

or

= 0.04+0.32+0.64

= 1
