explain how photosynthesis and cellular respiration work together
Answer: Photosynthesis makes a storable energy source, while respiration converts for individual cells. But because of photosynthesis and cellular respiration, energy from the sun is converted into a ATP that fuels the work of plant cells. Photosynthesis and respiration are both things that depend on each other. They both make what the other needs.
Explanation: Hope this helps have a wonderful rest of your day.
If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?
A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
D Nothing has to happen to the glucose. Plant cells can use it as is.
What happens to the glucose produced by plants?Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.
In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.

What is the relationship between the Earth, moon, and Sun during a solar and Lunar eclipse?
Answer: The relationship between the Earth, moon, and sun during a solar and Lunar eclipse is Lunar eclipses only happen once the Moon is in the opposite direction of the Sun in the sky, a montly occurence, which is known as a full moon.
Explanation: Once the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When this happens, Earth passes directly between the Sun and the Moon, which causes its shadow to create a lunar eclipse.
Answer:
during a luner eclipse the earth comes between the sun and the sun and the moon blockimg the sunlight falling on the moon.
Which of the following examples come from renewable natural resources
Answer:
Milk, Leather, Paper, Cardboard
Explanation:
Milk, leather, paper, and cardboard all come from natural resources for the largest part:
Milk - Cows
Leather - Animal hide
Paper - Trees
Cardboard - Recycled paper
All of the mentioned are renewable because cows can breed, hide can be found on many animals, trees easily grow everywhere, and cardboard is made from recycled paper (which comes from trees).
Uranium, tin, iron, plastic, steel, and gold aren't renewable and (most of them) do not come from natural resources. Uranium is rare and only found in a limited source around the world, as well as other metals (tin, iron, steel, gold). As for plastic? Plastic is not natural nor renewable because it's created by man. All of the above mentioned (besides the answer) also takes thousands of millions of years to degrade naturally.

Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Where the offspring is:
50% Ss with short hair phenotype 25% SS with short hair phenotype 25% ss whose phenotype would be long hair.According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

An unidentified plant produces spores, has many cells, but does not have true leaves. What plant is it?
A. liverwort
В. fern
C. gymnosperm
D. angiosperm
An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.
What are angiosperms?Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.
The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.
Therefore,An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for 9 amino acids.
Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids
