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.

if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm

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.
Explanation:
How can gene flow, genetic drift, and natural selection all influence macroevolution?
Answer:
Macroevolution refers to large-scale evolutionary changes that break the species barrier and can give rise to new species and even affect higher taxonomic groups.The basic evolutionary mechanisms migration, genetic drift and natural selection can produce important evolutionary changes if given enough time.Large groups and macroevolutionary trends originate in gradual, adaptive stages, as a product of natural selection acting at the level of individuals , but operating for much longer periods of time.All depends on the mutations originating new alleles or genes, which imply the existence of very different characters from the pre-existing ones, and that these different characters are selected because they imply a better adaptation to the environment.
Explanation:
Macroevolution refers to the evolutionary changes that occur on a large scale, such as the genesis of high-ranking taxonomic groups: the appearance of species within their taxonomic groups, the appearance of evolutionary trends, the acquisition of anatomical characteristics that characterize the groups.For there to be an evolutionary change, then, new properties must emerge that constitute a new species. Evolution is a process of changes at the species level, distinct from those that occur in each individual organism. Gene flow is the transfer of alleles of genes from one population to another. Contributes to variation and diversity of individuals. Evolution is then the change of allelic frequencies over time.Macroevolution takes place through the process of natural selection, that is, the differential reproduction of individuals, and adaptive improvement over a very long period of time. This type of evolution is based on interpreting the appearance of new species or large groups, as well as mass extinctions, with the subsequent proliferation of new groups. The evolutionary changes that determine the origin of body plans are based on macromutations on which natural selection acts.

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.

The type of RNA that delivers amino acids to the ribosome during protein synthesis is tRNA.a) trueb) false
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.

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.
