Prey animals are often smaller than their predators and have less physical strength, speed and defenses than the predators. Therefore, prey animals have to rely on various adaptive features to avoid being detected by predators. One successful way to avoid predation is to not be seen, and a prominent adaptation that helps prey not be seen is (A) camouflage.

Camouflage is a widespread defense mechanism among animals, wherein an organism blends with the surroundings to remain unseen by predators. There are various forms of camouflage that animals use to avoid being detected by predators. One of the most common forms of camouflage is coloration, wherein an animal has a color or pattern that resembles its environment.

The color of the fur, scales, or feathers of an animal that matches its background help it blend in with its surroundings and avoid being detected by predators. An example of this is the Arctic hare, whose white fur helps it blend in with the snow, making it difficult for predators like foxes to detect it.Another form of camouflage is shape and texture. Many animals have features that resemble the environment they inhabit.

For instance, some insects resemble leaves or twigs, while some fish have markings that make them blend in with their surroundings. An example of this is the stick insect, which looks like a twig, and the chameleon, which can change its color and pattern to blend in with its environment.

In conclusion, camouflage is a crucial adaptation that prey animals use to avoid detection by predators. Through coloration, shape, and texture, animals can blend in with their surroundings, making them invisible to predators and increasing their chances of survival. The correct answer is A.

Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.

Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.

Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.

Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A

Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.

One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.

EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.

Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.

While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

Answer: Neurotransmitters

Explanation: Neurotransmitters carry their information from the pre-synaptic neuron to the post-synaptic receiving cell.

Answer:

1. Carol is heterozygous for hemophilia. Her husband does not carry the allele for hemophilia. What is the probability that they will have a daughter with hemophilia? A son with hemophilia?

Solution:

Since Carol is heterozygous for hemophilia, she has one X chromosome with the hemophilia allele and one X chromosome without the hemophilia allele. Her husband, who does not carry the allele, has one X chromosome without the allele and one Y chromosome.

The probability that they will have a daughter with hemophilia is 0, as the daughter would need to inherit the hemophilia allele from both parents, which is not possible in this case.

The probability that they will have a son with hemophilia is 50%, as the son will inherit the hemophilia allele from Carol (who passes one of her X chromosomes to her son) and the Y chromosome from his father.

2. Jake suffers from red-green colorblindness. He married Janet who is not colorblind nor a carrier. What is the probability that they will have a daughter with color blindness? A son with colorblindness?

Solution:

Jake suffers from red-green colorblindness, which means he has a recessive allele for the condition on his X chromosome. Janet is not colorblind nor a carrier, which means she has two normal X chromosomes.

The probability that they will have a daughter with color blindness is 0, as the daughter would need to inherit the recessive allele for color blindness from both parents, which is not possible in this case.

The probability that they will have a son with color blindness is 50%, as the son will inherit the recessive allele for color blindness from Jake (who passes his X chromosome to his son) and a normal copy of the X chromosome from Janet.

3. William suffers from hemophilia. He married Sandra who is a carrier of the trait. What is the probability they will have a son with the disorder?

Solution:

William has hemophilia, which means he has a recessive allele for hemophilia on his X chromosome. Sandra is a carrier of the trait, which means she has one normal X chromosome and one X chromosome with the hemophilia allele.

The probability that they will have a son with hemophilia is 50%, as the son has a 50% chance of inheriting the hemophilia allele from Sandra (who passes one of her X chromosomes to her son) and a 50% chance of inheriting the Y chromosome from William.

4. Which of the following could be the parents of a colorblind female?

a) A normal male and a normal female (not a carrier)

b) A normal male and a female carrier

c) A colorblind male and a normal female (not a carrier)

d) A colorblind male and a female carrier

Solution:

A colorblind female can only occur if she inherits the recessive allele for color blindness onboth of her X chromosomes. Therefore, the only possible parents of a colorblind female are a colorblind male and a female carrier (option d).

Option a is not possible because both parents are normal and do not carry the color blindness allele. Option b is not possible because the female carrier would need to pass on the recessive allele for color blindness to the daughter, which is not possible as the daughter would inherit a normal X chromosome from the father. Option c is not possible because a normal female cannot carry the recessive allele for color blindness.

Hope this helps!

For any recessive disease to occur it is necessary that both the recessive alleles are expressed in the individual. 1) probability of a hemophilic daughter is 0  and a son is 50%. 2) Probability of a color-blind son is 50% and a daughter is 0. Hemophilic son - 50 %. 4) Option D is correct.

1) The probability that they will have a hemophilic daughter is zero. This is because to express the hemophilic trait one allele of the trait must be inherited from both the parents, but here the mother is a carrier while the father does not carry any allele for the disease.

The probability that they will have a hemophilic son is 50%. This is because he will inherit an X chromosome from his mother who is a carrier of the disease and one Y chromosome from his father.

2) The likelihood of having a color-blind daughter is 0 because the daughter would have to inherit the color-blind recessive allele from both parents.

The likelihood of having a color-blind son is 50% because the son inherits the color-blind recessive allele from Jake (through his X chromosome) and the normal X chromosome from Janet.

3) The likelihood of having a hemophiliac son is 50% because the son inherits 50% of the hemophilia gene from Sandra (passing one of her X-chromosomes to the son) and 50% of the Y-chromosome gene from William.

4) A colorblind woman can only become a colorblind woman if she has a recessive gene for color blindness in both her X-chromosomes. So, the only parents of a female who is colorblind are male and female carriers of the recessive gene.
