Phagocytes often do not recognize bacterial cells with capsules, increasing the likelihood they will survive and cause disease. What other benefits could capsules give bacterial cells?
Answer: Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.
Explanation:
Most microorganisms such as bacteria, virus, and parasites, are free living that benefits both plants and animals. The microorganisms that have the ability to cause disease are called pathogens. Infection occurs when pathogens are able to establish itself in a person through the use of its virulent factors. A typical example of virulent factors include the CAPSULES.
Capsules are made up of polysaccharides which lines the outer layer of a bacteria cell envelope. Example of such bacteria includes:
--> Streptococcus pneumoniae,
--> Klebsiella pneumoniae,
--> Haemophilus influnzae, and
--> Neisseria meningitis
These bacteria secrete a capsule around their cell wall which helps to prevent opsonization and phagocytosis by phagocytes of immune system of the host. This helps them to survive and cause disease. Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.

I NEED HELP PLZ ITS DUE TODAY. The sun produces a great amount of energy with sound and lights. We enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun. Explain this phenomenon in terms of mechanical waves and electromagnetic waves. (10 Points)
Answer:
See explanation
Explanation:
First of all, we have to know the difference between a mechanical wave and an electromagnetic wave.
A mechanical wave requires a material medium for propagation. It does not travel through space. An electromagnetic wave does not require a material medium for propagation and it can travel through space.
Light and heat are electromagnetic waves. They both belong to the electromagnetic spectrum. On the other hand, sound is a mechanical wave.
While heat and light can travel through space, sound can not because it is a mechanical wave. Sound has to pass through gas molecules and there is no gas in outer space.
Hence, we enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun.

Fruit color in a particular plant is controlled by a set of three quantitative traits that work in an equal and additive manner. Each trait has two alleles (i.e., A and a); each allele represented by a capital letter produces one dose of yellow pigment, while alleles represented with lower case letters do not produce any pigment at all. How many different shades of yellow fruit color are there
Answer:
7
Explanation:
The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A).

How would the population of this type of plant be affected if the bee
population decreased dramatically?
A. Because the plants depend on the bees as a food source, the plant
population would decrease.
B. Because the plant would not reproduce as effectively, the plant
population would decrease.
C. Because the two organisms are of different species, the plant
population would be unaffected by the change in the bee
population.
D. Because the bees would no longer prey on the flowers, the plant
population would increase.
Answer:
Option B - because bee act as a medium for the plant for fertilisation due to which plant reproduce but if the population of bee decrease this will affect the rate of reproduction in plants.
The population of this particular type of plant be affected if the bee population decreased dramatically because the plant would not reproduce as effectively, and the plant population would decrease. Thus, the correct option is B.
What is Population?A Population may be defined as the group of individuals belonging to the same species living in the same area at a given time. This represents the members of the same species in a definite area.
The population of bees is significantly necessary for mediating the process of pollination that involves the mechanism of sexual reproduction in plants.
But if the population of bees is reduced due to any factor, this plant does not undergo the process of pollination which ultimately leads to the reduction in the population of this plant as well.
Therefore, the correct option for this question is B.

Which of the following statements about metabolism are true? 1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy. 2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. 3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. 4) All organisms require an external source of energy, such as glucose or sunlight, for metabolic energy.
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).

List all six stages of the sensory pathway when an animal responds to information about its environment.
Explanation:
There basically four stages of sensory pathway when an animal responds to information about its environment.
and these stages of pathway are Reception, transduction, transmission, and perception.
The sensory receptors are commonly described as specialised neurons found in sense organs that helps detect and respond to stimuli. The six stages of the sensory pathway which an animal responds to information about its environment are:
Reception: This falla under sensation. It is simply a type of sensory receptors detect that stimulus is present.Transduction: This also falls under sensation. It is a type of sensory receptors whose work is mainly to convert stimulus energy into electrochemical energy.Transmission: This falls under sensation. It is when neural impulses leave sensory organs and moves to the brain.selection: This falls under perception. It acts as detectors that filter the stimuli by responding to particular features of a stimulus while also ignoring the rest.Organisation: This falls under perception: It is known to organise the characteristics of sensory stimuli in a meaningful manner. Interpretation: This Fall also under perception. It is known to give meaning to sensory stimuli.Sensation is simply regarded as a physiological process that uses sensory receptors in detecting and responding to stimuli.
Perception is referred to as the mental work of organising and interpreting sensory stimuli, making it meaningful.

how do the rates of photosynthesis change with the physical environment?
Answer:
Without enough light, a plant cannot photosynthesis very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.
