Answer: b. Necton
Explanation:
Necton is the term used to refer to aquatic organisms that are able to swim against the current of the water they are in. For this reason they are called "actively swimming" organisms. Aquatic plants that are unable to move against the current are called Plankton.
Fish, whales and dolphins are able to move against the current and so are classified as Necton. It is worthy of note however, that some organisms are able to transition from Plankton to Necton as they mature.

1. Coronary blood flow is subjected to an auto- regulation. ADVERTISEMENTS:
2. The pressure head (aortic pressure minus coronary sinus pressure)
3. Phasic blood flow
4. Chemical factors (blood gases), the most important one being the oxygen supply (hypoxia) and decreasing in oxygen tension (fall in pO 2 ). ...
5. Sympathetic stimulation
Explanation:
I put five so you have some to choose from
Answer:
Obtructions like fats in the arteries
Streght of the natural pacemaker to pumb blood
Low pressure which slows the circulation of blood
Explanation:
Carbon dioxide is carried in blood plasma.
Human blood also contains red blood cells and white blood cells.
Explain how the structure of red blood cells and white blood cells is related to their function.
(6 marks)
Answer:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

If you are observing worms, ants, and caterpillars, you are studying a biological _________________.
A. community
B. species
C. individual
D. population
E. none of the above
If you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.
What is Biological species?Biological species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
A Community may be defined as a group of individuals belonging to different species living in the same area. A Population may be defined as the number of the same species living in the same area at a particular time.
Here, worms, ants, and caterpillars are organisms of different species with different characteristics such as mode of nutrition, reproduction, and response to the environment.
The biological species are considered as an integral part or component of an ecosystem. The greater the biodiversity in an ecosystem, the greater the stability of the species within that ecosystem.
Therefore, if you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.

In pea plants the allele for round seeds (R) are dominant to the allele for wrinkled seeds (r). The allele for yellow seeds (Y) is dominant to the allele for green seeds (y). A heterozygous yellow, round seed plant is crossed with a seed that is green and wrinkled.
RrYy x rryy
What are the gamete combinations for the heterozygous parent?
A. RY, rY, Ry, ry
B. rr, yy, YY
C. Ry, ry, yy
Answer:
The correct answer is - A. RY, rY, Ry, ry
Explanation:
Gametes are the sex cells or reproductive cells that are haploid in number. Gametes carry only one allele of each gene or chromosome in any organism. The male gamete called an egg or ovum whereas the male gamete called sperm or pollen.
In this case, the heterozygous plant has the genotype RrYy. In each of the gametes, there would one allele of each gene. The gametes get a dominant R and a dominant Y allele and a recessive r and a recessive y allele. Each produces 25% each of RY, Ry, rY, and ry.

Acute meningitis is consistent with all of the following except: a. organisms could be endogenous b. organisms can spread from pneumonia c. symptoms are insidious, occurring over a period of weeks d. organisms spread from otitis media
Answer:
c. symptoms are insidious, occurring over a period of weeks
Explanation:
Acute meningitis is an ailment caused by viral or bacterial organisms. These organisms are responsible for the inflammation of the brain and spinal cord tissues and is usually life threatening.
The disease causing organisms could be endogenous, spread from pneumonia or otitis media. The symptoms however aren’t insidious which means occurring over a period of weeks . The symptoms usually lasts for some hours to a few days.

Solid liquid separation of microbial product in industry using filtration and centrifugation techniques?
Answer:
Filtration.
Explanation:
Filtration can be used to separate solid part from liquid part of microbial product because it is less time consuming. This filtration process can easily separate liquids from solid material by allowing liquids to pass through the small holes and collecting solid on the surface of sieve. centrifugation techniques are used to separate liquids of different densities so it can't separate solid from liquid, it can only be done by filtration process.

The diagram below shows a cross-section through an alveolus and a capillary. Why does oxygen move from P to Q?
Answer:
Diagram pleassseeeee
Explanation:
Answer:
The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick, so the exchange surfaces are very thin, and they are in close contact with each other. Oxygen therefore diffuses quickly through the alveolar walls and into the capillaries.

In the Linnaean system of classification, camels are members of the order Artiodactyla and the family Camilidae. Llamas are also members of
the family Camilidae. Based on this information, are llamas members of the order Artiodactyla?
а No, because every family member is classified into a different order.
b Maybe, because families and orders are separate and unrelated taxa.
с Maybe, because some but not all family members are classified in the same order.
d Yes, because all family members are classified together in the same order.
Answer:
The correct answer is - Yes, because all family members are classified together in the same order.
Explanation:
In the Linnaean system of classification, there are 7 taxa that are kingdom, phylum or division, class, order, family, genus, species. In these taxa, the kingdom is most inclusive and species is least inclusive taxa.
Order is more inclusive than the family which means various organism families make the order. If a family all the members are classified under the same order. Order have different families and each family have a different genus and so on.
