What characteristics do you expect to observe with a microscope if you investigate the division of mitochondria and chloroplasts in eukaryotic cells
The characteristics of mitochondria is that it has an oval shape bounded by double membrane while chloroplast have a green color.
What are Organelles?These are vital parts of the cell as they perform various functions required for the survival of the organism.
The mitochondrion has an oval shape while chloroplasts are green due to the presence of the green pigment known as chlorophyll which is used for photosynthesis.

The rate at which an object weathers is determined by many different variables. For example, compare the two ancient Egyptian structures below.
Compare the obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).
Both structures were carved in Egypt from the same type of rock more 1,000 years ago. However, the obelisk in New York, which was transported there from Egypt in 1881, has since experienced a much higher rate of weathering. What factors likely sped up the weathering process for the structure that was moved to New York?
Answer:
I just answered this question in your other submission of the question. You can look at it if you want!
The obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).In New York temperature is low,considerable cloudiness with occasional rain showers.
What are factors that can speed up the process of weathering?The amount of rainfall and the temperature can influence how quickly rocks weather. The pace of chemical weathering is accelerated by high temperatures and heavier rainfall. 2. Compared to comparable rocks living in cold, dry climates, rocks in tropical regions exposed to heavy rainfall and high temperatures weather far more quickly.
Chemical weathering is accelerated by moisture. Hot, humid regions are the ones that weather the fastest. In hot, dry areas, it happens extremely gradually. Ice wedging is not possible without temperature variations.
Significant influences in weathering include physical forces like temperature and humidity, chemical forces like oxidation and carbonation, and biological forces like animal and human activity-related burrowing.
Thus,In New York temperature is low,considerable cloudiness with occasional rain showers.

The tralt in the pedigree above is

Answer:
Looks like a recessive trait, since both halves of the shape needs to be filled to make the trait active.
The pedigree is explained in the image, and the male is represented by the square and the female is represented by the circle. Here is the sex linked recessive pedigree present in the image.
What does the pedigree explain?The pedigree explains the heritable pattern of traits, such as genetic diseases in males and females, as well as the chances of being diseased, such as with sex-linked recessive diseases, where males have a higher chance of being diseased than females. Here the image explains it is a sex-linked recessive disease because most females are carriers, which means they have a single copy of the recessive allele, but when they pass it on to their sons, they get fully diseased as they need a single recessive copy due to the presence of a single X chromosome.
Hence, the male is represented by the square, and the female is represented by the circle, and here is a sex linked recessive pedigree present in the image.

Tall oak trees are better able to compete for sunlight in crowded forests. short oak trees are at a
disadvantage. what type of selection appears to have made oak trees grow tall?
a. stabilizing selection
b. directional selection
c. disruptive selection
The type of selection that makes tall oka trees a better competitor for sunlight over short ones would be directional selection.
What is directional selection?It is a kind of natural selection in which individuals with traits at one extreme end of the population are better adapted to the environment.
In this case, tall and short oak trees are at the two extreme ends of the population mean with tall oak trees being able to better competitors for sunlight than the short ones.
The selection is, thus, directional, towards the tall trees rather than the average or the short ones.

Brown coat color rabbits possess the dominant allele B, and white coat color rabbits possess the recessive allele b. If the frequency of the allele for white coat color is 0.04, what is the frequency of the dominant allele in the population?
Assuming Hardy-Weinberg equilbrium, we have
p + q = 1
where p = frequency of dominant allele and q = frequency of recessive allele. So
p = 1 - q = 1 - 0.04 = 0.96
Consequently we have
• p² = 0.9216 = frequency of hom ozygous domininant genotype
• pq = 0.0768 = frequency of heterozygous genotype
• q² = 0.0016 = frequency of hom ozygous recessive genotype
since
p² + 2pq + q² = 1
What is the correct order of structures that a piece of food would encounter as it travels through the alimentary canal of a bald eagle?.
The correct order of structures is mouth, oesophagus, crop, stomach(proventriculus), gizzard, intestine, and anus.
The digestive tract of birdsThe digestive tract of birds starts from the mouth and ends at the anus.
As the food enters the oesophagus through the mouth, it is pushed down to the first stomach called the proventriculus.
Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and start the process of breaking down the structure of the food material.
Food substances that are hard to digest are transferred to the gizzard. Nutrients are absorbed in the intestines and undigested food substances are removed through the anus.

Glomerular filtration regulation involves intrinsic control which could best be described as ______.
The kidney's intrinsic capacity to control blood flow gives the ability to regulate glomerular filtration.
What is renal autoregulation?Renal autoregulation is a mechanism that allows the kidneys to maintain constant blood flow and glomerular filtration rate (GFR). This is hugely important to keep homeostasis for several reasons:
The right blood flow and GFR are necessary for excreting metabolic wastes, which avoids poisoning. It is key to maintain the electrolyte balance by finely regulating water and ions reabsorption.In case of high arterial pressure, autoregulation protects the glomerular capillaries from suffering an injury.Mechanisms involved in renal autoregulationTwo mechanisms take part in Renal autoregulation:
Myogenic response: preglomerular arterioles (especially at the level of afferent arterioles) can sense elevations in transmural pressure, which induces their contraction.Tubuloglomerular feedback: when the tubular fluid reaches the macula densa located in the distant tubule, the cells on it can detect changes in the concentration of sodium chloride, which is dependent on flow rate, and induce a modification in the diameter of the afferent arteriole.In conclusion, blood flow and glomerular filtration are two hugely important factors in renal function and both can be regulated by the kidney itself via two mechanisms.
