Does venueles carry bright red color?

Answers

Answer 1

Answer:

No

Explanation:

Arteries typically carry oxygenated blood, which is bright red in colour. The exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs.

Answer 2

Answer:

Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

if the carrying capacity for the north atlantic cod on the grand banks of newfoundland is 500,000 tons, when do you expect that the rate of population growth would be greatest?

Answers

If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, then we would expect that when there are 250,000 tons of cod on the grand banks, the population growth will be greatest.

The carrying capacity speaks volumes about the maximum amount of a species population that the ecosystem can sustain permanently provided there is the availability of water, food, habitat, and other life essentials.

In terms of population ecology, it is defined as the maximum burden that the environment can tolerate.

In population ecology, populations normally decrease above the carrying capacity while they increase below the carrying capacity. A decline in population size above the carrying capacity can be caused by a variety of factors, such as a lack of sunshine, space, or food availability.

Therefore, we can conclude that If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, the rate of population increase will be maximum and greatest when there are 250,000 tons of cod on the Grand Banks.

One of the hottest ideas in engineering today is the concept of building an energy capturing system
similar to photosynthesis. The system would use light energy to make artificial food. What two
parts would such a system need, and how must these parts interact if they are to be like
photosynthesis?

Answers

The capturing device and converter are the two parts needed by the energy capturing system in order to make food.

If an energy capturing system wants to perform the same function of photosynthesis, then it must have two parts i.e. converter and capturing device. The capturing device works to capture or absorb light energy and send it to the place where this energy energy is converted into food.

The second part is the converted which convert light energy into food particles. These two parts interact with each other then the desire product will e achieved otherwise not so we can conclude that capturing device and converter are the two parts needed by the energy capturing system in order to make food.

Answers

Answer:

An algal bloom.

Explanation:

The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria)  because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.

In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.

The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.

Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.

A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n) ________ species.

Answers

Answer:

vulnerable would be the answer

Currently, there are more than 1,300 species in the US that are either endangered or threatened. Species that are in risk of going extinct include those plants and animals that have become so scarce.

What Endangered Species Act, as a vulnerable species?

A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.

Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.

A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.

Therefore, A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n)(vulnerable) species.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?

Answers

Answer:

They use the glucose they have stored from previous photosynthesis reactions.

Explanation:

The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).

What is light-independent/dark reactions?

Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.

The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.
