4. Why does semen contain fructose?
A. Fructose breaks down to provide energy for the penis.
B. Fructose travels with the sperm to feed the egg before it is fertilized.
C. Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
D. Fructose provides energy for the development of the fertilized egg.
I’ll give brainiest:)
Answers
Answer:
The answer is C
Explanation:
I just got it right on the quiz
Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.
What is fructose?Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.
The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

1. Which of the following statements about classification of organisms is true?
A: Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
B: The Linnaean system of classification takes into account ancestral relationships between organisms
C: Linnaeus concentrated on the genetic characteristics of organisms to classify them.
D:In phylogenetic classification, the group that organisms are put into is called a taxon.
Answers
Answer:
Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Explanation:
took the test
The correct option is (a) Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Phylogeny classifies species based on evolutionary kinship or evolutionary distance (taxonomy). The degree and type of evolutionary distance between organisms determines their phylogenetic connection. Let's define taxonomy in order to better comprehend this idea.The connection between classification and phylogeny?The study and comparison of traits as well as the comparison of groups of organisms are the foundations of both phylogeny and categorization. However, there is a distinct feedback between character interpretation and inferred phylogeny, which is seen in the weighting of the characters used to construct the classification.

What might happen at the cellular level of the plant if there was no water available for photosynthesis?
Answers
Answer:
when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.
Explanation:
If there was no water available for photosynthesis, the cellular level of the
plant will be affected negatively in areas such as shrinking of cells and
decrease in photosynthetic activities.
Plants require water to produce food in the process known as
photosynthesis. When there is no water the photosynthesis is slowed down
and the cells begin to shrink.
The shrinking of cells then results to the wilting and yellowing of leaves of the plant.

What are similarities and differences between the structures of DNA and RNA?
Answers
Answer:
The similarities and differences between DNA and RNA are given as follows:
Explanation:
Similarities:
Both are made up of nucleotides
Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.
Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines
Purine binds with pyrimidines
Differences
DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring
RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.
DNA is double-stranded while RNA is a single-stranded
Under alkaline conditions, DNA is stable while RNA is not stable.

Could environmental factors, such as the lab's lighting or temperature, have had an effect? State these possible sources of error and analyze or estimate how much they may have affected your results.
Answers
Answer:
Yes.
Explanation:
Yes, measurements should be more accurate if these scientific error are removed. Yes, we must perform more trials in order to verify the experiment. Environmental factors, such as the laboratory's lighting or temperature, has a great effect on the experiment and can cause error. In this experiment the errors occur such as instrumental, environmental, procedural, and human. All these error causes inaccurate readings of experiment so greatly affect the experiment.

When blood is flowing through a vena cava, which main blood vessel will it flow through next?
A hepatic portal vein
B hepatic vein
C pulmonary artery
D pulmonary vein
Answers
Answer:
C.
Explanation:
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.
10. Deafness in cocker spaniels is inherited. The allele for deafness (d) is recessive to the allele for hearing (D). Two cocker spaniels that are heterozygous for hearing are mated together. What is the chance that a puppy will be deaf?
Question 10 options:
0%
25%
50%
100%
Answers
Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
The chance that the puppy will be deaf is 25%. The correct option is B.
What is allele?The term "allele" refers to the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to categorize the alleles.
We usually refer to them as normal or wild-type alleles, or abnormal or mutant alleles.
If they are both heterozygous, they have the Dd genotype. As per the Punnett square Dd x Dd, one can see the the following genotypes for the puppy:
DD, Dd, dD, dd
Because deafness is recessive, the puppy must be dd, which is 1/4 of the population.
Thus, the correct option is B.

Heriberto wanted to compare the gravity on the moon to the gravity on earth which statement below is correct
Answers
This question is incomplete; here is the complete question:
Herberto wanted to compare the gravity on the Moon to the gravity on Earth. Which statement below is correct?
The gravity on Earth is less than the gravity on the Moon.
The gravity on Earth is greater than the gravity on the Moon.
The gravity on Earth is equal to the gravity on the Moon
The gravity on Earth is the same as the gravity on the Moon.
The correct answer is The gravity on Earth is greater than the gravity on the Moon.
Explanation:
One of the factors that most affect the gravity (the force that makes objects move towards the center of a body) of planets like Earth or smaller bodies such as the moon is the mass. Indeed, if the celestial body is more massive or contains more mass the gravity force is stronger. Now, the mass of Earth is higher than the one of the moon. This makes the gravity of the moon weaker. Indeed, the gravity on Earth is 9.8 meters per square second, while the one in the moon is 1.62 metes per second, which is about 1/6th of the gravity on our planet.
