Small, nonpolar hydrophobic molecules such as fatty acids
a. pass readily through a
membrane's lipid bilayer
b. diffuse very slowly through the lipid bilayer
c require special channels to enter a cell
d. are actively transported across cell membranes
c. must enter the cell via endocytosis
Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer. Therefore, the correct option is option A.
The hydrophilic (water-loving) heads of the two layers of phospholipids in the lipid bilayer face outward towards the aquatic surroundings, while the hydrophobic (water-hating) tails point inward towards one another. The hydrophobic tails of phospholipids share characteristics with nonpolar hydrophobic compounds like fatty acids. These tiny molecules can easily dissolve in the hydrophobic area of the lipid bilayer because of their hydrophobic nature.
Therefore, the correct option is option A.

Answer:
D
Explanation:
Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor in order to signal a target cell to change its behavior. These are examples of hydrophilic hormones in animals: A. tyrosine-derived epinephrin and norepinephrin B. insulin and glucagon C. serotonin and melatonin (tryptophan-derived mammalian neurotransmitters D. All of the above E. None of the above
Answer:
The correct answer is - D. all of the above.
Explanation:
Hydrophilic hormones are the hormones that can not pass through the cell membrane as they are poorly lipid-soluble and cannot pass through cell membranes and bind the receptors present on the surface of the membrane.
Insulin and glucagon are peptide hormones that bind to a receptor in the target cell's membrane surface. Norepinephrine and epinephrine are catecholamines that are hydrophilic in nature. Seratonin and Melatonin are also bound on the surface receptor due to their hydrophilic nature.

Answer:
the answer to that would be a heterozygous organism.
Explanation:
Answer this question please quickly
Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.

how does the method of obtaining energy for fungi differ from that of plants and animals?
Answer:
From animals they need energy to get it fungi they can make it
Explanation:
Answer:
Fungi obtain their energy from absorbing either dead or living organisms.
Explanation:
Fungi are heterotrophic, meaning they cannot produce their own food, unlike plants. Plants are able to perform photosynthesis to obtain their energy by converting carbon dioxide and water into oxygen and glucose. However, unlike animals who go out to either hunt or forage food (for example, a deer eating grass or a wolf hunting a bunny), fungi absorb nutrients from dead or living organisms. For example, a fungi might be seen next to a decaying oak log. Or, it might be seen on the bark of a living tree.
You went running on a hot day. After your run, you sit down and feel very warm. How is homeostasis reacting?
Answer:
When you run, your muscles use energy and contract. This contraction and use of muscle fibers produces heat, lactic acid, and carbon dioxide. Your body will attempt to correct homeostasis by sweating to cool down your body (When the water in your sweat evaporates, it takes some heat energy with it), you breath harder to get rid of the excess carbon dioxide, and your blood attempts to clear the lactic out of your muscles.
What happens to the moon if Earth’s mass decreased?

if earth's mass decreased, then the moon would go further away.

the gravitational force of earth depends on its massif the mass decreased, then the gravitational force would also decrease which means that the moon would go further awaygravity is the reason why the moon is close to the earth and why we can see it at night(I HAVE 20min TO ANSWER THIS, NEED HELP) Based on the field lines, what are the charges of the
objects?
OX: positive
Y: negative
OX: negative
Y: positive
O X: negative
Y: negative
OX: positive
Y positive
Answer:
X: positive
Y: positive
Explanation:
The charges of the objects are:
OX: positive
Y: negative
The concept of electric field lines is a way to visualize the electric field around a charged object or group of objects. Electric field lines point in the direction of the electric field at each point, and the density of the lines corresponds to the strength of the electric field.
By following the direction of the field lines, we can make an inference about the relative charge of the objects. For example, field lines that originate from a positive charge will terminate on a negative charge, while field lines that originate from a negative charge will terminate on a positive charge.
Therefore, based on the field lines, we can determine that:
Option 1 is incorrect, as the field lines terminate on a negative charge.
Option 2 is incorrect, as the field lines originate from a negative charge.
Option 3 is incorrect, as the field lines originate from a negative charge and terminate on a negative charge.
Option 4 is correct, as the field lines terminate on a positive charge.

Question 7
In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.
Elephants live grouped in herds. This is why it is so difficult for a lone elephant living at a circus or exhibit. What type of population distribution do we call animals that live in herds, schools or other groups?
A
random
B
uniform
C
clumped
D
density cluster
Answer:
clumped
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment. Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.

What results from meiosis of a diploid cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell
