Answer:
Saprobionts eat by secreting enzymes through the cell membrane onto their food, a process known as extracellular phototropic digestion. The enzymes catalyze the breakdown of food into molecules small enough to be absorbed by passive diffusion, transport, osmotrophy, or phagocytosis.

You are carrying a case of 24 bottles of water up the stairs to your third-story apartment. What type of contraction are the muscles in your arms experiencing
Answer:
Concentric contraction.
Explanation:
Concentric contraction is a type of contraction that the muscles in arms experiencing when an individual lifting 24 bottles of water up the stairs. A concentric contraction is a type of muscle activation that creates tension on your muscle as it shortens. As your muscle shortens, it produces enough force to move an object in the upward direction. In weight training we can easily see concentric movement.

While snorkeling in the ocean you find large, leafy organisms that are brownish in color growing in large masses. You are unsure whether they are protists since they look quite plant-like. If they are actually protists, what characteristic will the organism's cells exhibit?
A. Each of the cells in the organism will have its own nucleus.
B. The cells will form a colony with separate groups of cells doing various jobs.
C. The cells will form a colony without differentiating into separate tissues.
D. Most of the cells in the organism will have cilia or flagella.
Answer:
A. Each of the cells in the organism will have its own nucleus.
Explanation:
While snorkeling in the ocean you find large, leafy organisms that are brownish in color growing in large masses. To be sure that they are protists since they look quite plant-like, the characteristic that the organism's cells exhibit will be that each of the cells in the organism will have its own nucleus.
This is because protists are eukaryotes, which simply means it has its own nucleus and are usually single celled.

Answer: this is a long one lol
Explanation:
purple flowers and round seeds could be both PPRR and PpRr because it's both dominant traits and heterozygous genotypes still show the phenotype of the dominant gene. purple flower and wrinkled seeds would be PPrr or Pprr for the same reason. white flowers and round seeds would be ppRR or ppRr, and finally white flowers and wrinkled seeds would be pprr. hope this helped :)

The statement that there must be a preexisting cell in order for a new cell to form is known as cell
Answer:
cells duplicate so when there is no cell it cant make any
Explanation:
The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.
What is cell theory?The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.
They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.
Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.
We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

An adult giraffe (Giraffa camelopardalis) has a heart that lies approximately 2 m below the top of the head when its neck is fully extended. Calculate the minimum diastolic pressure that a giraffe must have (in mm Hg). Hint: what is the absolute minimum blood pressure a giraffe could have at the very top of its head
Answer:
159.01 mmHg
Explanation:
position of Heart = 2m below the top of the head given that the neck is fully extended
Determine the minimum diastolic pressure
Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m
= 21200 kg/m^2
convert the value to Pa
21200 kg/m^2 = 21200 Pa
( 1 pa = 0.00750062 mmHg )
Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg
The minimum diastolic pressure that a giraffe must have is 150 mmHg
Diastolic Blood pressureDiastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.
The minimum diastolic diastolic blood pressure = absolute minimum blood pressure a giraffe could have at the very top of its head.Pressure formulaP = hpg
where;
P = pressure
h = height difference
p = density
g = acceleration due to gravity
Density of blood = 1000 kg/m^3
h =2.0 m
g = 10 m/s^2
Pressure = 1000 × 2.0 × 10
Pressure = 20000 Pascal or 20 kpa
Converting to mmHg1 kpa = 7.50 mmHg
20 kpa = 20 × 7.50
Pressure = 150 mmHg
Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg

why are electrons in an atom involved in bonding
Answer:
The valence electrons have a role in the bonding of two atoms. The nuclei of each atom are drawn together by their attraction to the valence electrons of the other atom. As the atoms are drawn together by their attractions, electrons from each atom are drawn to the nuclei of both atoms, where they are "shared."

In the lung alveoli, the oxygen partial pressure is about 100 mm of mercury, or 0.13 Atm. If blood was solely composed of a saline solution (lacking any hemoglobin), oxygen equilibrates with the alveolar air to a concentration of about 3 mg/L or 0.093 mm). In oxygen-saturated blood, however, the O2 concentration is about 0.008 M (8 mm).
Required:
a. What is the Henry's Law constant for oxygen in saline?

In human populations of northern European origin, the disorder called hemochromatosis causes excess iron uptake from food and affects one in 200 adults. Among individuals 15 to 50 years old, men are ten times as likely as women to suffer from iron overload. Part A Taking into account this range of ages, what explains this difference
Answer:
Females of reproductive age lose iron through menstrual blood
Explanation:
Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.

Answer:
Increase in sea level on the low lying countries which leads to degradation and salinification thereby making the soil non-arable. Meanwhile on the mountain regions, melting glaciers caused by rain falling on snow leads to mountain floods, avalanches and extreme rockslide and thereby disrupting agricultural produce and wildlife.
