Think about the bone marrow.
Answer:
D. Skeletal
Explanation:
blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
Costa Rica, located in Central America, features a very high level of biodiversity due to its tropical climate and large range of habitats. As a result, Costa Rica has endless examples of population interactions lurking in its rain forests. Read about three of these interactions, and then complete the sentences that follow. SlothTickCoral snake Brown-throated sloths (Bradypus variegatus) are tree-dwelling mammals and one of the least active animals on earth. Sloths spend most of their time sleeping or eating young leaves from the trees they live in. The interaction between the sloths and the leaves they eat is an example of a relationship. In this example, sloths are that acquire their nutrients and energy from the they eat. The colors of coral snakes provide these animals with to avoid predation. Specifically, their coloration helps them . The interaction between the hosts and the ticks that live on them can be characterized as , because .
Answer:
The interaction between the sloths and the leaves they eat is an example of a predator-prey relationship. In this example, sloths are herbivores that acquire their nutrients and energy from the plants they eat. The colors of coral snakes provide these animals with mimicry to avoid predation. Specifically, their coloration helps them advertise their toxicity. The interaction between the hosts and the ticks that live on them can be characterized as parasitism, because one species feeds on the other.
Explanation:
Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.
Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.
Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Remember hydrophilic will color those areas that "like water", think about water`s relationship with fats).
Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.

Scientists believe that there are three jeans what contribute to skin color in humans.
Which of these best describes the inheritance pattern of skin color?
A. Multiple allele in which offspring recessive three allele from each parent.
B. Multiple allele in which offspring recessive three allele from only one parent.
C. Polygenic in which offspring recessive three allele from each parent.
D. Polygenic in which offspring recessive three allele from only one parent.
Answer:
C. Polygenic in which offspring receive three allele from each parent.
Explanation:
In genetics, a polygenic inheritance is an inheritance that involves more than one gene i.e. more than one gene controls a particular trait. This is the case of the skin color trait in humans, which is controlled by three genes.
However, since each gene contains two alleles, each parent will contribute three alleles for the three genes to the development of an offspring i.e. three alleles from the father and three from the mother will result in three genes in the offspring, each containing two alleles.

Explanation:
how do the rates of photosynthesis change with the physical environment?
Answer:
Without enough light, a plant cannot photosynthesis very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.

Phagocytes often do not recognize bacterial cells with capsules, increasing the likelihood they will survive and cause disease. What other benefits could capsules give bacterial cells?
Answer: Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.
Explanation:
Most microorganisms such as bacteria, virus, and parasites, are free living that benefits both plants and animals. The microorganisms that have the ability to cause disease are called pathogens. Infection occurs when pathogens are able to establish itself in a person through the use of its virulent factors. A typical example of virulent factors include the CAPSULES.
Capsules are made up of polysaccharides which lines the outer layer of a bacteria cell envelope. Example of such bacteria includes:
--> Streptococcus pneumoniae,
--> Klebsiella pneumoniae,
--> Haemophilus influnzae, and
--> Neisseria meningitis
These bacteria secrete a capsule around their cell wall which helps to prevent opsonization and phagocytosis by phagocytes of immune system of the host. This helps them to survive and cause disease. Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.

List all six stages of the sensory pathway when an animal responds to information about its environment.
Explanation:
There basically four stages of sensory pathway when an animal responds to information about its environment.
and these stages of pathway are Reception, transduction, transmission, and perception.
The sensory receptors are commonly described as specialised neurons found in sense organs that helps detect and respond to stimuli. The six stages of the sensory pathway which an animal responds to information about its environment are:
Reception: This falla under sensation. It is simply a type of sensory receptors detect that stimulus is present.Transduction: This also falls under sensation. It is a type of sensory receptors whose work is mainly to convert stimulus energy into electrochemical energy.Transmission: This falls under sensation. It is when neural impulses leave sensory organs and moves to the brain.selection: This falls under perception. It acts as detectors that filter the stimuli by responding to particular features of a stimulus while also ignoring the rest.Organisation: This falls under perception: It is known to organise the characteristics of sensory stimuli in a meaningful manner. Interpretation: This Fall also under perception. It is known to give meaning to sensory stimuli.Sensation is simply regarded as a physiological process that uses sensory receptors in detecting and responding to stimuli.
Perception is referred to as the mental work of organising and interpreting sensory stimuli, making it meaningful.

a cross that results from a yellow and a purple allele together will result in what color corn kernel?
1.) yellow
2.) purple
3.) orange
4.) doesn’t exist
Answer:
1.) yellow
Explanation:
The high possibility of corn kernel colour is yellow if the yellow colour allele is dominant because the dominant trait or allele always appear in the offspring while on the other hand, the recessive allele does not appear in the shape and structure of the offspring so we can say that dominance is the reason for the appearance of colour in the seed or kernel.

3. The Amazonian rain forest is a captivating natural habitat rich in wildlife diversity. Around 3600 different spider species inhabit the area and one of these species of the Laluca lokita. This species is characterized by its great strength and territorial aggressiveness as well as its powerful venom. Within the species, the brown colored abdomen is dominant to the recessive black colored abdomen. Throughout the study of these arachnids, scientific research also found that hairy legs is dominant to hairless legs in this species. During the mating season, a brown, hairy male spider mates with a black, hairless female. In the F1 generation, all of the progeny are brown and hairy. When the progeny of this generation is able to reproduce, a male spider of the F1 generation mates with a black, hairless female. When the resulting progeny are observed for these two traits, 180 are brown and hairy, 185 are brown and hairless, 188 are black and hairy, and 182 are black and hairless. What are the genotypes of the two original parents

what two things can happen to the food made by plants?
Answer:
Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration
Answer:
The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide
The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.

3. Which of the following is NOT a method that has been used to predict earthquakes?
A) Trying to observe precursors such as foreshocks and changes to animal behavior.
B) Watching changes in weather patterns.
C) Using past earthquake patterns.
D) Predicting stress accumulation based on how recently an earthquake occurred.
Predicting stress accumulation based on how recently an earthquake occurred is not the method that has been used to predict earthquakes. The correct option is D.
What is earthquake?Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault.
The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.
Erratic animal behaviour, such as fearful or puzzled pets, or birdcalls not typically heard at night, can be a clue that an earthquake is about to happen. Water levels in wells or artesian bores suddenly change.
It hasn't been possible to anticipate earthquakes by basing stress accumulation on how recently an earthquake happened.
Thus, the correct option is D.

In chickens, comb shape is determined by alleles at two loci (R, r and P, p). A walnut comb is produced when at least one dominant allele R is present at one locus and at least one dominant allele P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant allele is present at the second (genotype rr P_). If two recessive alleles are present at the first and at the second locus (rr pp), a single comb is produced.
