The predatory bacterium Bdellovibrio bacteriovorus drills into a prey bacterium and, once inside, digests it. When the predatory bacterium attacks the gram-negative bacterium, what are the first structures penetrated by B. bacteriovorus on its way into the prey's cytoplasm
Answers
Answer:
The outer membrane, a peptidoglycan layer, periplasm, and cell membrane
Explanation:
The predatory bacterium will have to penetrate the cell wall and the cell membrane of the gram-negative bacterium before getting access to the cytoplasm.
In order to penetrate the cell wall of a gram-negative bacterium, the predatory bacterium will have to penetrate the components of the cell wall which consists of an outer membrane, a thin peptidoglycan layer, and a gel-like matrix known as the periplasm.
Thereafter, the predatory bacterium will have to penetrate the cell membrane before eventually getting access into the cytoplasm of the prey bacterium.
The peptidoglycan layer or the outer membrane will be the first structure penetrated by the B. bacteriovorus.
The attack of the predatory bacterium on the other bacterium:In the given case, the predatory bacterium, that is, B. bacteriovorus needs to penetrate the cell wall and the membrane of the gram-negative bacterium prior of getting within the cytoplasm of the host bacterium.
To penetrate the cell wall of a gram-negative bacterium, the predatory bacterium have to infiltrate the cell wall components comprising,
An outer membranePeriplasm, that is, the gel-like matrixA thin peptidoglycan layerThus, the predatory bacterium will first have to penetrate the peptidoglycan layer of the gram-negative bacterium.

You are in your room listening to music and, realize you are thirsty, you can feel that your soda is no longer cold, and you decide to invite a friend over. What parts of the central nervous system would be primarily involved in each of these italicized behaviors
Answers
Answer:
Internal region of the brain and the hypothalamus are related to the sensation of thirst.
Thalamus is involved with the perception that the soda is not colder.
Explanation:
The central nervous system is the body system responsible for making your body receive information and respond appropriately, promoting full bodily functioning. It is formed by the brain, spinal cord and the components that form them.
Regarding the activities shown in the question above, we can say that some components of the brain are related. For example: The innermost part of the brain and the hypothalamus are related to feeling thirsty. This is because the inner part of the brain is responsible for making the brain understand how the organism is functioning, if something is missing or if there is any discomfort that needs to be resolved. The hypothalamus, in turn, is responsible for the release of hormones that signal that your body's homeostasis is unbalanced. With the interaction of these two structures you realize that you are thirsty.
In addition, the thalamus is responsible for allowing your body to receive sensory messages. It is this structure that allows you to realize that your soda is not cold when you touch the glass, or take a sip of it.

Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quickly in a single reaction. C. It releases its energy slowly through multiple reactions, allowing it to last longer. D. It has more energy.
Answers
Answer:
B. It releases its energy quickly in a single reaction.
Explanation:
Adenosine triphosphate (ATP) is an energy carrying molecule in living systems while Glucose is an organic molecule (carbohydrate) that stores a high amount of energy. Glucose is a monosaccharide and the smallest unit of carbohydrate-containing foods we eat. Chemical energy is stored in the chemical bonds that hold the glucose molecule.
However, during the process of cellular respiration, energy stored in glucose molecule is broken down and transferred to ATP, which stores energy between the phosphate bonds of its molecule. The energy in ATP is released to perform cellular activities when the phosphate bond of the last phosphate molecule is broken.
Although the glucose molecule stores way more energy than ATP molecule, the ATP molecule releases its energy quickly in a single reaction. This makes energy readily available for cellular functions. This property of ATP makes it an active energy source over glucose.
Answer:
B. It releases its energy quickly in a single reaction.

In coral reefs, clownfish live unharmed among the poisonous tentacles of sea anemones. The sea anemones protect the clownfish from predation, while the clownfish scare off predators, such as the butterfly fish, which would otherwise eat the anemones. The clownfish may also provide important nutrients to the anemones. This arrangement is an example of which symbiotic relationship
Answers
Answer:
The sea anemone and the clownfish live together in a type of symbiotic relationship called mutualism, where both species benefit from the other. The sea anemone offers the clownfish protection and leftover food
The anemone's tentacles provide the clownfish with protection from predators, while the clownfish chase away butterfly fish that would eat the anemone. ... Sea anemones can do very little to control the flow of water across their bodies, and they rely on local currents to bring in oxygen and nutrients.Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting.Instead, both species have evolved behaviors that help them avoid being eaten while they graze for benthic algae. Butterflyfish typically swim in pairs near a particular clump of coral. ... An anemone robbed of its clownfish guards will quickly fall prey to the voracious butterflyfish.

In a population of 200, 86 individuals express the recessive phenotype. What percent of the population would you predict would be
heterozygous?
A. 65%
B. 55%
C. 35%
D. 45%
Answers
Answer:
The correct option is;
D. 45%
Explanation:
From the Hardy- Weinberg law, we have;
p² + 2·p·q + q² = 1
p + q = 1
Where:
p = Dom inant allele frequency in the population
q = Recessive allele frequency in the population
p² = The percentage of individuals in the population that are hom ozygous dominant
q² = The percentage of individuals in the population that are homo zygous recessive
2×p×q = The percentage of hete rozyous individuals in the population
The number of individuals that express the recessive phenotype = 86
The number of individuals in the population = 200
The percentage of individuals that express the recessive phenotype, q² = 86/200 = 0.43
Therefore;
q = √0.43 = 0.656
p + q = 1
p = 1 - q = 1 - 0.656= 0.344
∴ The frequency of individuals that express the do minant phe notype, p = 0.344
The percentage of heterozyous individuals in the population = 2×p×q × 100 = 2 × 0.656 × 0.344 × 100 = 45.15% ≈ 45%
