Answer:
Eubacteia and Archaebacteria
Explanation:
A father has blond hair. A mother has black hair. Their three offspring have brown hair, blond hair, and red hair, respectively. Which pattern of inheritance could account for human hair color? Explain your answer.
Answer:
polygenic inheritance
Explanation:
The pattern of inheritance that could account for human hair color according to the illustration is polygenic inheritance.
In polygenic inheritance, multiple alleles (the alternate versions of the same genes) controls the trait for hair color. Individuals that inherit different combinations of alleles from the same parents will have different hair colors.
In this case, there are alleles that determines blond hairs, black hairs, brown hairs, and red hairs. All these alleles are alternate versions of the same gene. The father could be carrying blond/brown alleles and the mother is carrying black/red alleles or vice versa, their offspring will exhibit different hair color depending on which allele is dominant or recessive.
why the relative numbers of mitochondria found in a muscle cell would be larger than the relative number found in a fat cell.
Answer:
The ATP is produced in the mitochondria using energy stored in food. ... Some cells have more mitochondria than others. Your fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.
Explanation:
Describe the sequence of events during a blood clot.
Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
Platelet plug. ...
Fibrin clot.
Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis.
Answer:
Cryptosporidium parvum is an apicomplexan pathogen that obtains glucose either directly from its host or by the degradation of polysaccharides.
Explanation:
C. parvum only can produce ATP by glycolysis. Lactate dehydrogenase (LDH) is a universal enzyme required to synthesize pyruvate, which is the final product of the glycolysis process. This enzyme has been subject of research to understand the metabolism and evolution of apicomplexan parasites, including C. parvum.
Cryptosporidium parvum is a pathogenic agent that causes the disease cryptosporidiosis. The pathogen obtains glucose directly from the host. It can also obtain by the breakdown of polysaccharides.
C. parvum produces ATP through glycolysis. The enzyme lactate dehydrogenase is used by the C. parvum to generate metabolic ATP. It generates this ATP through the glycolytic pathway. The enzyme allows the conversion of NADH to NAD+. NAD+ is necessary for glycolysis to produce ATP. Metabolic energy plays a crucial role in the growth and proliferation of the pathogen in the host.
Some of the features of C. parvum are:
It consists of a unique lactate dehydrogenase enzyme to yield ATP. It causes the disease in the gastrointestinal tracts. The pathogen is used for research and understand its ability to obtain ATP directly from the host.Therefore, C. parvum consists of enzyme lactate dehydrogenase that helps in energy production through the glycolytic pathway.

Help please! I will give brainly! The prefix aqua- refers to ""water."" The verb culture means ""to foster the growth of living things."" Use this information to define aquaculture.
Answer: im not sure but i think it means to grow plant because it is talking the key words are to foster the growth of living things.
i hope it is right if not sorry!!!!!!!!!!!!!!!!!!!!!
Answer:
Aquaculture means to foster organisms (for the most part fish) that live in water.
Explanation:
After reading Holt Enviromental Science's Food and Agricultural Section: Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

Answer:
release energy,form molecules of ATP
Food molecules such as proteins cannot be absorbed unless they are digested.
Give one reason why.
Answer:
Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.
Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.
The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.
Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.
Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.

Q. Describe the double circulation in human beings.
Answer:Double circulation has two components, pulmonary circulation and systemic circulation. Pulmonary Circulation : It is movement of blood from heart to the lungs and back. Deoxygenated blood of the body enters the righ auricle, passes into righ ventricle which pumps it into pulmonary arch,...
Explanation:
Answer:
During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature. During a single cycle, the blood goes twice in the heart. This double circulatory system is important because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
There are 4 types of breezes: land breeze, sea breeze, mountain breeze and valley breeze.
The breeze will originate from an area of high pressure and travel towards/blow in the direction of the area at a lower pressure.
In each case, the name of the breeze indicates where the breeze is blowing from. For instance, the land breeze will blow from the land (at high pressure) to the sea (at lower pressure). A mountain breeze will blow from mountain (at high pressure) towards the valley (at low pressure).

the diagram shows three steps in the clotting process.
Which lists the clotting process in the proper order?
o А, С, В
ОВ, А, С
o С, А, В
е В, С, А
Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.

In a desert ecosystem, coyotes and rattlesnakes both eat the same type of mouse as a primary part of their diets. Recently, coyotes have been hunted and killed by people, decreasing the overall coyote population. How will this most likely affect the rattlesnake population over time?
Answer:
Answer: It will increase because coyotes are the competition.
Explanation:
An ecological niche can be defined as the functional role which an organism performs in the ecosystem in order to sustain it's life. The functional roles include how an organism obtains it's food, type of food eaten by the organism, type of habitat chosen by the organism and type of breeding season used by the organism.
In the given situation, both coyotes and rattlesnakes are dependent upon the same ecological niche that is they are dependent upon mouse as a primary part of their diets. As, both coyotes and rattlesnakes are dependent upon the same diet there may exist the competition between the two species. But it is mentioned that the coyote population is decreasing therefore the population of rattlesnake will most likely increase as the competition for the same diet decreased.
