(a) A cell where PKB is always active has a mutation that results in the permanent activation of GSK3. Based on the information in Figure 2, predict the effect of this mutation on the activity of glycogen synthase. Justify your prediction.
Answer:
a. Normally, PK2 activates PK1. We are told that PK1 and PK2 normally work sequentially in an intracellular signaling pathway. If PK1 is permanently activated, a response is seen independently of whether or not PK2 is present. If PK1 activated PK2, no response should be seen if PK1 were activated in the absence of PK2.
GSK-3 is an unusual protein kinase in that it displays high, “constitutive” activity in unstimulated cells and is rapidly inactivated upon a variety of cellular stimulations. The most thoroughly documented pathway for the inactivation of GSK-3 is in response to insulin and is mediated by protein kinase B (PKB, also termed Akt), which lies upstream of GSK-3 [8].
A cell wherein the PKB seems to be constantly active does indeed have a disorder that makes GSK3 to be permanently activated. Kinases, for example, control glycogen synthase as well as glucose acid phosphatase.
GSK3, as well as glycogen synthase kinases 3, is however one enzyme that is controlled through PKB phosphorylase kinases.Throughout one cell, PKB seems to be constantly in motion, culminating in GSK3 regulation, which would, in turn, be responsible for glycogen synthase activities only through the signaling cascade.
Thus the response above is correct.

When a whale dies, its body often falls
to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale
fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed
on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath
the whale body, and bacteria feed on the whale bones.
At a deep-sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which
of the following? Select all that apply.
A. a population
B. part of a community
C. part of an ecosystem
Answer: c. Part of an ecosystem
Explanation: the fish, crustaceans, molluscs and bacteria are part of a community, but sand is not. Each of those species is part of a population.
Answer:
I would say B and C
Explanation:
Like all ecosystems, all organisms depend on each-other. Living or non-living all animals depend on each-other.

Emily's body starts to develop secretory glands at the end of the milk ducts in the breasts. Based on the given information, we can say that Emily is most likely to be in the _____ stage.
Answer:
Thelarche
Explanation:
In females, thelarche represents the start of puberty and as such it marks the beginning of the secondary development of the mammary glands known as breasts. This pubertal development usually occur in females that are between the ages of 8 years and 12 years due to the secretion of hormones such as estrogen.
In this scenario, Emily's body starts to develop secretory glands at the end of the milk ducts in the breasts. Based on the given information, we can say that Emily is most likely to be in the thelarche stage because she is beginning to experience breast budding.
When will natural selection occur? A. When there is no competition B. When a population reaches carrying capacity C. When there are plenty of resources D. When there is no variation in a species
Answer:
B because when it hits its carry capacity its survival of the fittest to live
When a population reaches carrying capacity.
What is Natural selection?
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
One way to explain the millions of species that have existed on Earth is through natural selection.
The idea of evolution by natural selection is credited to Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913), who co-wrote a paper on it in 1858.
Therefore, When a population reaches carrying capacity.

They originated from Central and parental regions of the brain which is part of the cerebral cortex and they are refer to slow wave sleep. They can occur in the third stage of sleeping. They are deeply penetrated like drum beat and occur during deepest meditation and dreamless dream.
The major mechanism of action of anandamide appears to be: Group of answer choices presynaptic facilitation. postsynaptic facilitation. presynaptic inhibition. postsynaptic inhibition.
Answer:
presynaptic inhibition
Explanation:
Presynaptic inhibition is an inhibitory mechanism capable of modulating neurotransmitter release in the central nervous system (CNS), i.e., by suppressing the release of neurotransmitters from axon terminals. Endocannabinoids are neurotransmitters that bind to receptors in other cells, thereby indirectly affecting the activity of other neurotransmitters. Anandamide is a neurotransmitter derived from arachidonic acid -an omega-6 fatty acid-, whose effects are mediated by cannabinoid receptors in the CNS. This major endocannabinoid (anandamide) is thought to inhibit the release of the inhibitory neurotransmitter γ-aminobutyric acid (GABA).
) What kind of approach to phylogeny reconstruction is ribosomal RNA sequencing: cladistic or phenetic
Answer:
cladistics
Explanation:
Cladistics is a phylogenetic approach used to classify groups of organisms based on shared derived characteristics (synapomorphies) that are not present in distant ancestors. Cladistics describes evolutionary relationships between organisms. Ribosomal RNA genes such as, for example, 5S ribosomal RNA, are appropriate for phylogenetic (cladistic) analyses because they are evolutionarily conserved between related species. Using ribosomal RNA genes, it is possible to trace evolutionary relationships ranging from kingdom level to genus. Unlike cladistics, phenetics is a method used to classify organisms based on the degree of similarity between them (usually by using external and/or morphological/observable phenotypic traits), regardless of their evolutionary relationships.

Describe what role do humans have in protecting or changing this issue? Explain steps or plans you would implement.
Here are a few examples of ideas you could discuss:
Climate change
Habitat destruction
Invasive species
Pollution
Overpopulation
Overconsumption-exploitation
Answer: Humans can address and resolve the issues related to their environment and social problems.
Explanation:
Climate change: The climate change is caused by the seasonal change or due to human oriented activities like burning of fossil fuels related to liberation of green house gases this is related to global warming.
Human beings can take initiative of utilizing less fossil fuels, planting more trees so that they can absorb more carbon dioxide gas which is a chief green house gas responsible for raising the temperature.
Habitat destruction: The habitat destruction happens when the habitat is destroyed due to forest fire, volcanic eruption, earthquake or cyclone.
Humans can build strong houses by keeping in mind the hazards can influence the building where they are living.
Invasive species: The invasive species is the one which is introduced into the new environment due to human effort or naturally. The invasive species reduce the population of the native species by competing for resources.
The humans can determine whether the invasive species can possibly affect the members of the native species or not. Possible measures can be taken to reduce their population by selective hunting.
Pollution: The contamination of air, water, and soil by the action of polluting agents is called pollution.
The pollution can be reduced by reducing or restricting the sewage and industrial discharge in water, stopping or reducing the use of fossil fuel which on burning produce contaminating gases, and reducing the use of polythene bags which can contaminate the soil.
Overpopulation: The overpopulation is condition in which the population of the species exceeds the carrying capacity of the region. The carrying capacity is the ability of the ecosystem to sustain a particular number of members of the species depending upon the availability of resources.
The overpopulation in case of humans can be controlled by use of contraceptives, small family rule adaptability, and by stopping early marriage as this can offer long reproductive period to couples.

A family has a Y-linked disease that affects the father. What is the chance of a male offspring inheriting the same disease?
Answer:
100%
Explanation:
A sex-linked trait is a trait which is inherited on the sex chromosomes (X and Y chromosomes). This means that that trait is only inherited by offsprings of a particular sex. In this question, a family is said to have a Y-linked disease that affects the father.
Note that, Y chromosomes are only present in the male sex, meaning that a father will always transfer its Y chromosome to all his male offsprings. Since this disease (trait) is on the Y chromosome, it means that all male offsprings i.e. 100% of this father will have the disease.
Fur color in animals is frequently controlled by more than one gene. However, brown fur in rabbits is dominant over white fur. A white female gives birth to all white rabbits, even though the father had brown fur. Show how this is possible.
Answer:
Please find how this is possible in the explanation below
Explanation:
This question is regarding a gene in rabbit coding for fur color. Brown fur (B) in rabbits is dominant over white fur (b). However, according to the question, a white female gives birth to all white rabbits, even though the father had brown fur. This is possible because the father is heterozygous for the brown fur i.e Bb.
Hence, in a cross between a heterozygous father (Bb) and a white mother (bb), the following gametes will be produced by the following parent:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the probability of 1/2 of the offsprings will possess white fur (bb). Based on this result, the white female is able to give birth to all white rabbits because the male rabbit contributed the white allele (b).
