Where does the bloody deposit the
oxygen and nutrients?

Answers

Answer:

The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

How are Gymnosperm and Angiosperm plants different?

Answers

Answer:

Hey! :D

Explanation:

The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants, which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, Torreya, Ginkgo.

3. Nucleic acid  -----------------------------------→ Nucleotide

Explanation:

Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.

Monomers are simple molecules that when joined together and form chains become polymers, a process called polymerization, which is mediated by polymerase enzymes.

Peptides and proteins are formed by the addition of specific amino acid sequences. Polysaccharides, or complex sugars, are formed by the addition of monosaccharides, such as glucose. A nucleic acid, such as DNA or RNA, consists of chains or strands that are formed by nucleotide sequences. Lipids are the polymerized form of fatty acids.

As part of an experiment, you grow some plants in an environment including carbon dioxide with radioactive carbon isotope 14C as a tracer. After a few days you take the plants out and look for the tracer. You find it primarily in the roots. How did it get there? Why is it in the roots?

Answers

Answer:

Plants make their own food with the help of photosynthesis, in which the organic carbon is formed from the inorganic carbon. Organic carbon is used as a source of energy and helps in various cellular functions.

Organic carbon mostly stored in the form of starch and other carbohydrates and also helps in forming the structure of the plants. The starch is stored mainly in the roots, fruits and stems. The main source of starch is in roots in tubers of the plants. The radioactive carbon that is found in the plant roots in the experiment is the excess carbon that stored in the roots of the plants

5. Besides being part of the composition of bone, why else do mammals need calcium?

Answers

Answer:

It's important for the contracting muscle

Explanation:

Besides being part of the composition of bones, calcium is needed by mammals for the following processes:

Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting.

What is Calcium in living organisms?

Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.

Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.

The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.

It also plays a critical role in blood clotting.

Therefore, it is well described above.

Why do heart cells have different characteristics than skin cells?
Heart cells have different DNA than skin cells.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Heart cells reproduce by mitosis.

Answers

Answer:

Heart cells express different genes than skin cells. B

Heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.

Humans as multicellular organisms possess different cells in our body system. These cells perform varying functions in the body.

The different functions performed by different cells is attributed to the cellular differentiation. Cellular differentiation is the process whereby an undifferentiated cell becomes specialized.

The cellular differentiation occurs due to the difference in gene expression in each specific cell. All cells contain the same DNA sequence, however, they are expressed differently.

Therefore, heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Solid:____
Fewspot:_____
White Overo:______

The images below show the same cell, before and after reaching equilibrium. Which statement best describes what happened as the volume of the cell increased

Answers

The missing part of the question and group of options is attached as an image.

Answer:

The correct answer is - D - The number of solvent particles outside the cell decreased.

Explanation:

As the solution reached equilibrium the concentration of the solute is equal inside the cell and outside the cell, so the number of particles of the solvent must increase inside and decrease outside of the cell.

The cell volume increased due to the flow of the solvent from outside to the inside of the cell this type of diffusion of solvent is known as osmosis which leads to the swollen or bigger cell.

Answer:

The number of solvent particles outside the cell decreased.
