Energy exists in different forms, some of which are electrical, heating, chemical, luminous, among others.
Chemical energy in biological systems is based on the formation-breaking of bonds: to form a bond, energy must be expended, while when a bond is broken, energy is released.
Often, these processes require the participation of enzymes within the organisms; enzymes are proteins that decrease the activation energy of a reaction. For example, if a lot of energy is needed to break a bond, the enzyme will help to lower the energy required.
In biological systems such as humans, the energy molecule is ATP, which releases energy when a bond is broken and a phosphate group is released, leaving ADP as a product. And although it is an efficient process, the laws of thermodynamics explain that no process is 100% efficient, and therefore, some amount of energy is always released in the form of heat. Unlike chemical energy, heat energy is not stored in bonds and cannot be catalyzed by enzymes or utilized by biological systems.

Some specifically selected hormones, cholesterol, LDL and iron enter cells via
A) exocytosis
B) endocytosis
C) pinocytosis
D) receptor-mediated endocytosis
Answer:
B) endocytosis
Explanation:
Endocytosis is the process through which things pass through the cell membrane and into the cell.
Endo = internal, within
Cystosis = referring to cells
Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endpcytosis.
Thus, Some plasma-membrane proteins can be efficiently absorbed and concentrated through endocytosis linked to clathrin coating.
This method transports iron-loaded transferrin protein and cholesterol-containing LDL particles linked to these receptors into the cell, and it also internalizes the low-density lipoprotein (LDL) receptor.
By using electron microscopy, it is possible to see the characteristic basket-like structure that the clathrin coat that forms on these structures creates. It is thought that the polymerization of the clathrin coat promotes changes in membrane curvature, surface membrane deformation, and vesicle formation.
Thus, Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endocytosis.

What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.
The chromosome is composed of two sister-chromatids.
During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.
The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.
explain the role of biotechnology in agriculture?
Biotechnology, at its most basic, is biology-based technology; biotechnology harnesses cellular and biomolecular processes to develop technologies and products that improve our lives and the health of our planet. The primary goal of modern biotechnology in agriculture is to improve the quality, quantity, nutrition, taste, and shelf life of produce, allowing stakeholders to achieve higher yield with lower energy costs.
This includes ancient agricultural processes such as fermentation as well as more recent examples of developing disease-resistant plant varieties through crossbreeding. Modern methods for improving agricultural practices through biotechnological progress include transgenic techniques, which revolve around the insertion of foreign DNA strands into the host genome to increase crop yield.
Agriculture biotechnology benefits include increased crop yield, reduced crop vulnerability to environmental stresses, improved nutritional qualities of food crops, improved taste, texture, or appearance of food, and reduced reliance on fertilizers, pesticides, and other agrochemicals.

a technologist is performing a body fluid analysis on a csf specimen recently received in the laboratory. four csf tubes were sent to the body fluids bench. the tech notices that all four specimens seem moderately blood tinged equally. moderate xanthochromia was also noted. what is the most likely reason for these findings?
The most common cause of xanthochromia, which manifests as a yellow, orange, or pink staining of the CSF, is the breakdown of haemoglobin into oxyhemoglobin, methemoglobin, and bilirubin as a result of RBC lysis.
Xanthochromic CSF: Is it typical?The yellowish staining of a centrifuged CSF specimen's supernatant is known as xanthochromia. It is abnormal and arises from the breakdown pigments oxyhemoglobin, bilirubin, and methemoglobin being released from RBC lysis into the CSF during Xanthochromia therapy. Treatment for xanthochromia entails addressing the underlying cause. If xanthochromia in the CSF indicates that the patient has a subarachnoid haemorrhage, they may have magnetic resonance imaging (MRI), CT angiography, or be sent immediately to the hospital for treatment.

describe the process of gaseous exchange between alveoli air and blood
The bloodstream receives oxygen from the lungs during gas exchange. Carbon dioxide leaves circulation enters the lungs. Between the alveoli and network of tiny blood arteries known as capillaries are the lungs.
What is the main function of gas exchange ?The waste gas carbon dioxide is exchanged for oxygen at each cell in your body. This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.
How is gas exchange in the body?While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body. The respiratory membrane serves as a barrier for the exchange of oxygen and carbon dioxide.

Question: what 3 organisms one could be found in Alabama’s biome?
Solution (explanation):
Let us remember that a biome is understood as each ecological unit into which the biosphere is divided according to a set of climatic and geological factors that determine the type of vegetation and fauna.
Alabama is one of the most biologically diverse states in the United States of America and is a global hotspot of diversity for several groups of plants and animals. In fact, this diversity is a product of Alabama's climate, geologic diversity, and rich evolutionary past. Alabama has more than 6,350 species.
One of the organisms in Alabama is the Salamanders which are one of several groups of southeastern organisms that are famous for their degree of speciation. In fact, the ecosystem of Alabama houses Red Hills Salamander.
On the other hand, the most dramatic evolutionary influence of the Southern Appalachian Mountains has been on Alabama's freshwater fauna. In fact, in Alabama, we can find fish, snails, mussels, and crabs because they are all easily isolated in the shallow streams in the headwaters of major rivers. Consequently, more freshwater species are found in the Southeast than anywhere else outside the humid tropics. Alabama is at the center of this aquatic biodiversity hotspot. In fact, speciation was especially rampant in the Tennessee River and Mobile River Basin. Therefore, another organism that we could find in the ecosystem of Alabama is the fish Vermilion Darter.
Finally, the region has more than 100 plant genera, for example, an example of another organism found in the Alabama ecosystem is the American beech.
Answer: we can conclude that the correct answer is: we can conclude that 3 organisms that one could be found in Alabama’s biome?
1. Red Hills Salamander.
2. Vermilion Darter.
3. American beech.

Cutting is the easy technology to produce large number of vegetative seedlings at a time . How explain
Many plants, especially horticultural and garden varieties, are propagated through cuttings; by the use of new techniques, many other plants formerly not susceptible to propagation through cuttings have more successfully reproduced. The plants that develop from cuttings are clones.
Explanation:The cutting method is a technique of vegetative reproduction in plants. In this method, a branch of the stem is cut out from the plant and buried in the soil. New leaves arise from the nodes in the stem and the new roots also develop giving rise to a whole new plant. Example- rose, sugarcane. Cuttings can be made from any part of the plant. Most frequently, however, either a stem or leaf is used. A stem cutting includes a piece of stem plus any attached leaves or buds. Thus, stem cutting only needs to form new roots to be a complete, independent plant. A cutting is a section of plants such as a modified stem, leaf, or root used for vegetative propagation that forms either adventitious shoots, adventitious roots (stem and single node cuttings), or both (root and leaf cuttings). These are long pieces of roots which are used to artificially propagate new plants. For example, lemon, orange, blackberry, boysenberry, raspberry, etc. Cutting gives young children independent movements of each finger. Cutting with scissors works on the separation of two sides of the hand and strengthens hand muscles. Bilateral coordination is also addressed when they have to hold the scissors in one hand and the paper in the other. The four main types of stem cuttings are herbaceous, softwood, semi-hardwood, and hardwood. These terms reflect the growth stage of the stock plant, which is one of the most important factors influencing whether or not cuttings will root. You will get greater uniformity (clones) of your plants. The plant will reach maturity at an earlier age. When a recipe specifies how to cut an ingredient, it is important to follow the instructions because using the proper cutting technique will affect the dishes cooking time and will help ensure the food cooks more evenly and maximizes flavour.
Cutting is the easy technology to produce large number of vegetative seedlings at a time because the plants which are not susceptible can be easily propagated through this.
What is Vegetative propagation?
Many plants, especially those of horticultural and garden varieties, are propagated through cuttings. By the use of new techniques, many of the other plants formerly those which are not susceptible to the propagation of plants through cuttings which have more successfully reproduced. The plants that develop from cuttings are clones.
Most of the plant cuttings include stem pieces, and these have no root system of their own, and are therefore likely to die from dehydration of plant parts if the proper conditions are not met. Plant cuttings require a moist medium, which, however, cannot be too wet as this can rot the plant cutting. A number of media which are used in this process include however are not limited to soil, perlite, expanded clay pellets, and even water if given the right conditions. Most of the succulent cuttings can be left in open air until the cut surface dries, which may improve the formation of root when the cutting is later planted.
