Answer:
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Answer:
Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts.
which of the following statements is FALSE?
a. alleles are made when one original DNA strand experiences mutations that result in phenotypes that offer advantages
b. the DNA of two alleles must be almost identical. since the trait is the same. But the effect of the allele may be very different!
c. in humans, for every trait we can only have two alleles. but that trait can be controlled by many alleles. there are no limits on how many alleles can control a trait.
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
e. if humans were diploid we would only have one allele per trait
Helpppp pleaseee
Answer:
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
Explanation:
Being diploid means humans carry two sets of chromosomes. Since we have both dominant and recessive gene types, humans can mask the effect of recessive alleles since the dominant trait will be seen in the phenotype or genotype since it is a dominant gene. The effect of the recessive allele will show up only if both diploid genes are recessive.

1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.
Red is dominant over yellow. If a male purebred red rose(RR) is crossed with a female hybrid rose (Rr), what percent of the roses will be red?
25%
100%
Btw i learned 50% and 75% is wrong so that is why there is only two
Answer:
100%
Explanation:
Because one of the roses is purebred dominant, all recessive genes will be overshadowed.
write a five sentence paragrgh explaining the cell cycle
Answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.
New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.
The two main parts of the cell cycle are mitosis and interphase.
Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”
The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.
Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.
Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

What is the relationship between genes DNA and proteins
Answer:
Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.
Hopefully, this answer helped! :D
Answer:
Most genes contain the information require to make proteins. The type of RNA that contains the information needed to make protein is called a messenger RNA or mRNA and it carries the message from the DNA out of the nucleus into the cytoplasm

energy transfer through molecule to molecule contact is called?
Answer:
It's called conduction
Explanation:

2) during...... glucose is broken down for it's energy and carbon dioxide released as ...
3) .... is the process that bacteria use to cause the decay of death organisms
Answer:Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

here are the structures i hope it helps
Answer:
primary, secondary, tertiary, and quaternary.
Explanation:
four levels of protein
1. primary structure of a protein: this is the number and sequence of amino acids held together by the peptide bond in a polypeptide chain.
2. secondary structure of a protein: this described the interaction of the sequence of amino acids in a polypeptide chain, and the bond formed is hydrogen bond.
3. tertiary structure of a protein this is a 3 dimension structure of a protein in the polypeptide chain and the bond formed are hydrogen bond, ionic bond and disulfide bond.
4. quartenary structure of a protein this is a combination of more than one structure which is primary structure, secondary structure and tertiary structure. bond formed are disulfide bond and so on.
