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.

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.

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?
Answer:
this is because the reactant substances gives equal products in the product side

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.

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.

Most Swiss starlings produce four to five eggs in each clutch. Starlings producing fewer or more than this have reduced fitness. Which of the following terms best describes this situation? (3 points)
The bottleneck effect will result in a small gene pool with little genetic diversity.
Directional selection will happen because the population individuals will be unable to adapt, leading to extinction.
Disruptive selection will result in the population of birds' risk decline, due to reduced number of eggs.
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. I think is D
Answer:
D: genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection.
Explanation:
Genetic diversity allows for birds to produce an ideal number of eggs, which leads to stabilizing selection. The correct option is D.
What is genetic diversity?The spectrum of various inherited traits inside a species is referred to as genetic diversity.
There would be many individuals with a wide range of different traits in a species with high genetic diversity. For a group of related species to adapt to changing environments, genetic diversity is mandatory.
Genetic diversity aids the populations to adapt to altering environments. More variation boosts the likelihood that some individuals in a population will have allele variations that are suited to the environment. Those people are more likely to survive and have children with that allele.
Birds can produce an optimal number of eggs due to genetic diversity, which leads to stabilizing selection.
Thus, the correct option is D.

Answer:
C. predation
Explanation:
The limiting factor that is being displayed when a fox chases a pika is predation.
Limiting factors can be referred to as those features in the environment which actually leads to the limitation in the growth, distribution or availability/abundance of an organism or population of organisms in an ecosystem.
In the predation limiting factor, as the population of the prey decreases, the population of the predator starts to decrease as well. In other words, we can say that one factor limits the growth of the other factor.

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.
