Answer:
The phopholipid tail is hydrophobic, since it is composed of two fatty acids.
Explanation:
Phospholipids are the fat molecules that mainly compose the cell membranes, forming a double layer.
The phospholipid molecules are formed by glycerol and phosphate group, located in the head, and a tail formed by fatty acids.
The pole formed by the phosphate group is hydrophilic —since it is polar in nature— while the end formed by fatty acids, the tail, is hydrophobic.
In the plasma membrane, the hydrophobic end is located towards the surface, while the hydrophilic portion is located in the center of the lipid bilayer.

How are cells, tissues, organs, and organ systems related to each other?
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Explanation:
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems. They all work together to make sure the human body is always in a good shape and always protected.

A) DNA B) prokaryotic C) lysosomes
Answer: B.Prokaryotic
Explanation:
in organisms with X and Y chromosomes, many more genes can be found on the X chromosome than on the Y chromosome. In mammals , how might this deviate from traits being expressed, according to mendel.
Answer:
See the answer below
Explanation:
The fact that many more genes can be found on the X chromosome than on the Y chromosome means that genes that are limited to the X and Y chromosomes do not follow the Mendelian pattern of inheritance.
For recessive traits, it will ordinarily take 2 recessive alleles for a gene to be expressed according to Mendel (other things being equal). For organisms with X and Y chromosomes, only one recessive allele is required on either of the 2 chromosomes for the gene to be expressed.
For dominant traits, organisms can be true-breeding or heterozygous when the trait obeys Mendel's law. Organisms with X and Y chromosomes only require an allele for the trait to be expressed and the opportunity to be true-breeding or heterozygous does not arise.
In mammals with XY chromosomes, organisms with XX chromosomes are homogametic and those with XY chromosomes are heterogametic. The X chromosomes are homologous to one another but not to the Y chromosome.
Thus, recessive X-limited traits are usually more commonly expressed in organisms with XY chromosomes (because only one allele is needed) while any individual that inherits the Y chromosome automatically inherits the trait for the genes that the chromosome carries.

Why is carbon special compared to other elements?
Answer: Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms
Explanation:
because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. Having the atomic number 6, every carbon atom has a total of six electrons.
Answer: Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
Explanation: Carbon's characteristics include its ability to bond with oxygen, hydrogen, nitrogen, phosphorus and sulfur. Carbon biochemical compounds are essential to all life on the planet. Carbon atoms can bond to one another and form different structures. Which is not a function of proteins.

11. What type of reproduction leads to genetic variation (differences) in a population?
A. Binary fission
B. Asexual reproduction
C. Sexual reproduction
D. Vegetative reproduction
Answer:
A. Sexual reproduction
Explanation:
Sexual reproduction promotes variable gene combinations in a population leading to genetic variation. Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
Answer:
C. Sexual Reproduction
Explanation:
I am not really good at explaining thing, so I had to get some help from g00gle, plus i'm sure it would better for you to learn from g00gle than me. : )
Sexual reproduction provide genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms.
It produces a great deal of genetic variation through the shuffling of both beneficial and deleterious mutations.
During the light-dependent reactions of photosynthesis, which event must occur for ATP synthase to function properly?
A. Hydrogen ions must pass through a channel within ATP synthase.
O
B. Molecular oxygen must combine with ATP synthase.
C. A molecule of ATP must release a phosphate group to become ADP.
D. Photosystem I and photosystem II must be deactivated.
In the light-dependent reactions of photosynthesis, the event that must occur for ATP synthase to function properly is that Hydrogen ions must pass through a channel within ATP synthase. Thus, the correct option for this question is A.
What is the light-dependent reaction of photosynthesis?The light-dependent reaction of photosynthesis may be defined as a type of reaction that utilizes light energy in order to make two molecules that are ultimately required for the next stage of photosynthesis.
The energy storage molecule ATP and the reduced electron carrier NADPH. In plants, light reactions take place in the thylakoid membranes of organelles called chloroplasts.
This reaction successfully processes the conversion of solar or light energy into chemical energy in the form of ATP and NADPH. In this process, hydrogen ions must pass through a channel within ATP synthase.
Therefore, the correct option for this question is A.

What is hurricanes?Hurricanes are hazardous and can result in significant storm surge, wind, rip current, and flooding damage.
They can take place anywhere in the Atlantic or Pacific oceans, including on any U.S. coast. In the past, storm surge has been the main factor in hurricane-related fatalities in the US.
People board up their homes, load up their cars, and evacuate as a powerful hurricane approaches the shore. For those who live in hurricane-prone regions, these storms can be disastrous. The strongest weather systems are hurricanes.
