Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?
Answer:
The majority of ATP will not form.
Explanation:
The poison leaf plant, also known as gifblaar contains fluoroacetic acid, a compound that shut down the Krebs cycle that leads to less production of ATP because Krebs cycle drives the formation of electron carriers. These electron carriers are very important because these electron carriers carry the energy that is used to create a large number of ATP molecules in the final steps of aerobic respiration so we can conclude that majority of ATP will not form due to poison.

Blood type is determined by multiple alleles and can be used to determine the possible parents of an offspring. In this case, the mother has blood type B, and her child has blood type A. There are two possible fathers for this child. The phenotype of one man is type O, and the phenotype of the other man is type AB. What is the genotype of the man who is the father?
A. IAIB
B. IAio
C. ioio
D. IBio
Answer:
A. IAIB
Explanation:
Since the child has blood type A and the mother is B, one man having blood type O makes it so that the child cannot be blood type A.
IAIB is the genotype of the man who is the father.
What are Genotypes?The type of variant present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it.
For illustration, BB, Bb, and bb could be used to denote a certain gene variant. The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype.
In a single experiment, the genotypes at millions of sites in a genome can be determined using DNA sequencing and other techniques. Some genetics influence an individual's phenotype, or observable traits.
Therefore, IAIB is the genotype of the man who is the father.

in the largest loss of energy that could otherwise be utilized by consumers?
A Movement
B. Homeostasis
C. Excretion
D. Respiration
Answer:
I think it is letter C
Explanation:
Correct me if I am wrong
The correct answer is option D. respiration as producers and other organisms of each trophic level most of their energy lose by metabolic reactions such as cellular respiration.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat as energy flow from one organism to another trophic level are consumed by organisms from the next level.
only 10% of energy transfers to the next trophic level.Regulation of homeostasis of the organisms is also one of the ways an organism loses their energyExcretion or feces is also one of the ways organism lose their energyMost of their energy lose by metabolic reactions such as cellular respiration.

What provides energy to muscles and helps keep
them strong?
Answer:
The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.
Answer:
adenosine triphosphate (ATP)
Explanation:
Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.
During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human chromosome. This map led to the discovery that the human genome is made up of about how many genes?
Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

Answer:
B. The increase is due to industrial point source pollution.
Explanation:
Pollution is the release of harmful substances into land, air or water. The harmful or toxic substances are called POLLUTANTS. According to this question, a community discovers via analysis that its river is now polluted with small amounts of over 20 different chemicals.
This chemicals is a pollutant that can likely emanate from industrial companies and industries that produces these harmful chemicals as waste. Hence, the increase is due to industrial point source pollution.
Use insulin and glucagon as examples, explain how negative feedback of these two hormones regulate the blood glucose level and maintains homeostasis. (No links or I'll Report
Answer:
glucagon works to counterbalance the effects of insulin.
Explanation:
when insulin is released, the blood sugar in the body decreases; however, when the blood sugar is low enough, the system instead releases glucagon which breaks down the stored sugar and balances the blood sugar level in the body. if the level goes too high then insulin will be released again.

1. Give an example of a behavior you observed in another person. When you looked at
their behavior, did you decide their action was more a result of circumstances, or their
personality? What information did you use to make your judgment? (6 points)
(its psychology btw)
Answer and Explanation:
The person to whom I observed a behavior that will be exposed in this response was a character from a show called "Reply 1988." This character showed a highly explosive behavior and was very nervous and stressed. I believe that this behavior is a result of the circumstances that this character was experiencing at the time, as he was under a state of great tension and stress, as he believed that his son had suffered a plane crash. In addition, this character has always shown a very calm and peaceful personality throughout his life, which shows that the explosive behavior was caused by the circumstances. To make this judgment I used the way the character behaves in his daily life and his interactions with other characters.

A)
These organisms have homologous structures and therefore have a recent
common ancestor.
B)
The DNA sequences for these two organisms will show 99% homology
since they both code for legs.
The legs of these organisms are analogous structures and do not represent
recent common ancestry.
The donkey and beetle do not share a recent common ancestor because the legs of these organisms have a common purpose but not a common structure.
What is locomotion?A person or object can move from one point to another through locomotion, which is directional movement. Numerous fields of science, medicine, and technology are influenced by the study of locomotion.
In biomimetics (also known as "biomimicry"), which is the creation of man-made procedures, materials, tools, or systems that mimic nature, the mechanisms of locomotion may be used. For instance, designers of robots mimic human movement to produce lifelike androids.
In virtual reality and video game art and design, locomotion is a crucial field of study (VR).

During meiosis, homologous chromosomes line up next to each other. In some
cases, one arm of a chromatid crosses over the arm of another chromatid. What is
the result of this process?
the independent assortment of genetic material
the creation of an additional sex cell
continuity in the offspring cell's DNA
additional variation in the DNA of each sex cell formed
Crossing over is a mechanisms involved in introducing genetic variation. When the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed. Option D.
---------------------------------------
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
So, according to this information, when the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed.

In pea plants, the allele for smooth pods (S) is dominant over the allele for constricted pods (s).
Which of the following pairs of terms are correctly matched?
Choose 1 answer:
Ss - phenotype; smooth pod - genotype
SS - genotype; constricted pod - phenotype
SS - phenotype; constricted pod - genotype.
SS - genotype; constricted pod - phenotype
Answer:
ss - genotype; constricted pod - phenotype
Explanation:
trust me Lol
Pea plants having gene control phenotype of pod shape S is dominant having phenotype smooth and phenotype constricted pods having s genotype, hence option d is correct.
What is the difference between genotype and phenotype?Phenotype is a physical observation of a trait which control by agene
and genotype is a genetic observation that can not be seen physically.
The allele which controls the phenotypic character of a plant is called the dominant over the other allele which can not show its expression, the allele is always present in a group but only the dominant will show its expression.
In a pea plant, if the allele for smooth is dominant over the other, it shows expression in allelic combination and masks the expression of constricted pods.
Therefore SS is the genotype and the constricted pod is the
phenotype, hence option d is correct.
