Identify organs of the urinary system.
Relate the organs with their
functions.
• The material this system uses to
maintain balance in the body.
Answer:
The kidney is an organ that is part of the urinary system.
Explanation:
The kidney's function is to filter out waste from your blood. It requires water and your blood to maintain balance in your body. The waste from your blood and the water will go out as urine.
Plants have low energy needs as compared to animals. Explain.
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

what will happen if the number of organisms decreased?
Answer:
it will affect the ecosystem in a bad way
Answer:
They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.

In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called ____. These structures help attract pollinators to the flower. The ___ is the female reproductive organ, which contains three segments: the stigma, style, and ovary.
Answer:
In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.
In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.
What is Female reproductive organ?One ovary is located on either side of the uterus in the majority of females. They have two primary functions: generating hormones and releasing eggs. They are roughly the size and shape of an almond.
At birth, two ovaries each hold about 700,000 immature eggs, or oocytes (Trusted Source). These eggs start to grow and mature inside the ovary follicles after a person reaches puberty.
A developed egg is released by the ovaries around once every month. The menstrual cycle includes a process called ovulation, which is what gives rise to eggs.
Therefore, In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.

can someone check if my dihybrid cross is correct?
Answer:
Yeah I believe it is
Explanation:
Answer:
Yes this is correct
Explanation:
Since the recessive genes are cancelled out by the dominant ones, the only possible traits are the dominant ones, so yes you did it correctly :)
Consider a population of 100 annual wildflowers, some yellow, some red. It is like other real populations, its gene pool is changing. For each of the scenarios below state which of the Hardy-Weinberg conditions the population deviates from, and explain what agent of microevolution causes the gene pool to change
Answer:
From normal to hybrid or different state.
Explanation:
According to Hardy-Weinberg conditions, the population deviates from present state to hybrid because of the change of gene pool. Genetic drift, natural selection and mutation are considered as agent of microevolution that is responsible for the change in gene pool. If the change in gene pool occurs the form and structure of population of organisms has to be change in its appearance.

5 How does the presence of coal on Antarctica indicate a climate change?
The discovery of a new coal deposit means people will be able to use this found fuel longer.
Coal forms from the remains of plants that lived in tropical swamps millions of years ago, Coal deposits can tell scientists what the composition of the atmosphere was in the past.
Coal is burned for fuel and it releases carbon dioxide into the atmosphere.
Answer:
The discovery of a new coal deposit means people will be able to use this fossil fuel longer.
Coal is burned for a fuel and releases carbon dioxide into the atmosphere.
Which cell structure of the zooxanthellae performs a vital function that also helps the coral polyp grow?
Answer:
photosynthesis
Explanation:
Zooxanthellae are not only responsible for providing energy via photosynthesis, but also take up nutrients released by the corals metabolism such as nitrogen and carbon dioxide.
A F1 pea plant carries Yy alleles for seed color. Explain
what would happen to these alleles during gamete
formation
Answer:
During the formation of the gametes (i.e. meiosis) we have the separation of the sister chromatids and the independent segregation of the alleles: this means that one of the gametes will carry the "allele Y" and the other the 'y allele"
The three arrows in the diagram each represent a process known as?
(1) mitotic cell division
(2) meiotic cell division
(3) fertilization of gamete cells
(4) differentiation of tissues
Answer:B
Explanation:
In cats, the allele (B) produces black color but (b) produces a yellow color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell color. The alleles (B) and (b) are sex-linked as well. Cross a tortoise shell female with a yellow male.
A.vWhat percent of their offspring will be yellow?
B. What percent of their offspring will be black?
C. What percent of their offspring will be tortoise shell?
D. Why is it impossible to have a tortoise shell male offspring?
Answer:
a. 50%
b.25%
c. 25%
d. Why is it impossible to have a tortoise shell male offspring? the x chromosome, a male can only have one copy of the allele - either B. orb, not both!
Explanation:
Alleles can be referred to as alternate forms of a gene. Incomplete dominance refers to two true-breeding parents crossed to give an intermediate phenotype.
The allele (B) produces black color but (b) produces a yellow color. A heterozygote produces a tortoise shell color (Bb)
Cross a tortoise shell female with a yellow male.
Bb x bb
Bb Bb bb bb
c. Bb --- 50% tortoise shell color
a. bb --- 50% yellow color.
b. No black -- 0%.
d. The males offspring cannot be tortoise shell because they have just the one X chromosome on which this gene resides. So they are either black or yellow.

Explanation:
Challenge: In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?

Iron is with one kind of atom that combines with oxygen from the air to form rust (iron oxide). Rust contains two types of atoms, which means it is .
Answer:
A compound
Explanation:
A compound is a substance (pure) that contains two or more different types of atoms chemically combined together. In other words, a compound is formed from the chemical combination of two or more elements.
According to this question, iron (Fe) is an element with one type of atom that combined with oxygen in the atmosphere to form iron oxide known as RUST. This is primarily what happens when a ironic substance is said to RUST. Rust is a combination (chemical) of two different kind of atoms i.e. iron and oxygen, hence, it is a COMPOUND.

People who have muscular dystrophy have something called a "mutation". How does that mutation arise
Answer:
The correct answer is - It can occur when the DNA is copied over there can be a problem that is not caught during cell division causing that makes the new DNA mutated form of the original version and the mutation can be ok or harmful.
Explanation:
DMD or muscular dystrophy is a recessive x liked genetic disorder that takes place due to mutation or the error in the genes during cell division and desired protein does not form called dystrophin.
It takes place due to an error in DNA replication and is not corrected or identified by the checkpoints of the cell division and expressed from the mutated form of dystrophin which is shorter than the original form.
