Whales, humans, lizards, and birds each have forelimbs that are adapted for different functions, including swimming, using tools, walking, and flying. While different in function, these forelimbs share a similar skeletal structure of the humerus, radius, and ulna. How does a comparison of the forelimbs of these organisms provide evidence for evolution?
A. These homologous structures indicate that these four organisms all share a common ancestor.
B. These analogous structures indicate that whales are descended from organisms that lived on land.
C. These analogous structures indicate that these four organisms all experienced convergent evolution.
D. These homologous structures indicate that humans, whales, and birds all evolved from a lineage of lizards.
Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.
Given RRYY x Rryy, what will the parents be? (no links please)
I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)
RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.
For Rryy :
Rr is heterozygous (the alleles are not the same), so the parents could be:
RR x rr
RR x Rr
Rr x Rr
(if you do a small punnet square, you can double check these!)
Since yy has both recessive alleles, the parent is yy as well.

7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
с
Between the first photograph and the second photograph, the Moon rotated so that less of
the light-colored rock on the Moon's surface faced Earth.
d
Between the first photograph and the second photograph, the Moon moved so that the
student astronomer was able to see less of the half that faces the sun.

Answer:yh it is b
Explanation:
A student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.
What is the significance of the moon revolution?The changing appearance of the moon over time is due to its changing position in its orbit around the earth, the light part of the moon appeared to shrink over time as the moon moved in its orbit, causing the illuminated part that faces the earth to diminish and the dark phase to appear.
Hence, a student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.

The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the tRNA by reaction with ATP activation of the amino acid by reaction with ATP interaction of the mRNA with the tRNA
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi
1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).

Which two structures are part of the cortisol pathway?
Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.
The structures that are part of the cortisol pathway are the hypothalamus and liver.
Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.
What structures are in the Cortisol pathway?The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.
The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.
The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.
Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.

Explanation:
Sewage sludge (biosolids) removed from a municipal wastewater treatment plant is a mixture of organic material and water. Research and explain why the incineration of sewage sludge may require more energy than it produces. Explain why people may be reluctant to use biosolids as a fertilizer for food crops.
Hey love! <3
Answer:
Sewage systems are used all around the world transferring waste to treatment plants where they are filtered and traded in for organic material. If the sluge were to be incinerated it could be repurposed, however the gas used to burn the sewage waste comes from condensing saturated fuel oil and requires 195 SCM of natural gas to successfully complete the chemical transfer. That's a lot of energy, and the natural process costs plenty more then what you're getting in returns. Through the process toxins can develop inside of the incinerated waste which could poison crops and animals, studies also show the process can release carbon monoxide into the air. To conclude it's called sewage waste for a reason, what goes down should stay down instead of putting what we eat and inhale at stake.
Hope this helps out! (ﾟヮﾟ) Sincerely, Kelsey from Brainly.

The incineration of sewage sludge may require more energy than it produces because of the high cost of energy.
Municipal wastewater treatment plants are estimated to consume more terawatt hours per year of electricity, which equates to about billions in annual electric costs. That's a lot of energy, and the results show that wastewater sludge able to produced up to 44.82 ml biogas/kg of sludgePeople may be reluctant to use bio solids as a fertilizer for food crops.

Which of the following is most likely to contribute to density-dependent regulation of populations? Group of answer choices Individuals voluntarily stop mating so that overcrowding does not occur. Density-independent factors lead to fewer births and increased mortality. The incoming energy decreases in populations experiencing a high rate of increase. Density-dependent factors lead to fewer births and increased mortality.
Answer:
Density-dependent factors lead to fewer births and increased mortality.
Explanation:
The carrying capacity can be defined as the maximum population size an environment can support. Density-dependent limiting factors produce a logistic growth pattern (S curve) in the population until it reaches its carrying capacity, thereby decreasing the birth rate and increasing the mortality rate in the population. Some important density-dependent limiting factors able to control the size of the population are competition (intraspecific competition), predation and diseases.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.
