Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.
which type of hormone diffuses across the plasma membrane and binds to receptors in the cytoplasm module 16.4c
Answer:
Steroid hormones.
Explanation:
Steroid hormones is a type of hormones that diffuses across the plasma membrane and binds to the receptors present in the cytoplasm. The hormones are released from the carrier protein and diffuse inside the cell across the lipid bilayer of the plasma membrane of the cells. The steroid hormones pass through the plasma membrane of a target cell and attached to the intracellular receptors located in the cytoplasm or in the nucleus.
how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

what is a skeleton and give two characteristics of a mammal
A skeleton is a structural frame that supports an animal body.
The skeletal system of mammals and other vertebrates is broadly divisible functionally into axial and appendicular portions.
There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable).
Fluid skeletons are always internal.
The presence of hair or fur.
A four-chambered heart.
Answer: well I know the skeleton is the bone structure in some living organisms if there a vertebrate
Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes
Answer:
lysosome
Explanation:
The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).

Why has the number of people in the world increased if the human population growth rate has decreased?
Answer:
Life expectancy has steadily risen.
People live longer lives.
To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.
The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.
Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:
Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.
Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

list few points on the importance of sun in power supply.
Answer:
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Answer:
Cerebral cortex.
Explanation:
The masses of gray matter that lie deep within the cerebral hemispheres is called cerebral cortex. The cerebral cortex is responsible for many brain functions such as sensation, perception, memory, association, thought, and voluntary physical action. Damage occur to cerebral cortex can leads to many cognitive, sensory, and emotional difficulties in the body. It is also responsible for regulating intensity and precision of voluntary movement.
If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.
Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.
What is permeability?Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.
The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.
The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.
Therefore, option C. the less permeable roads cause rainwater to become runoff.

66. A 64-year-old woman, who has always been proud of her suntanned, healthy look, is referred to a dermatologist with a blue-violet, painless, 1.5-cm lump in the skin of her left shoulder. The lump is firm and cannot be moved, and has grown very rapidly over the past few weeks. The mass is removed surgically and the pathologist diagnoses it as a Merkel cell carcinoma. If the UV radiation to which her skin was exposed affected the Merkel cells, what other cell type sharing the same specific epidermal layer might also be affected
Answer:
Basal stem cells for keratinocytes
Explanation:
Keratinocytes are epidermal cells located in the outermost layer of the skin (i.e., the epidermis). Moreover, the cells located in the basal layer of the skin are known as basal keratinocytes or basal cells. These basal cells are proliferative cells that undergo differentiation in order to form suprabasal epidermal layers. Merkel cells are neuroendocrine cells that are located in the basal layer of the skin (scattered among basal keratinocytes), which are attached to surrounding keratinocytes by intercellular junctions called desmosomes.
