Answers

Answer 1

Answer:

Environments on Earth are always changing, and living systems evolve within them. For most of their history, human beings did the same. But in the last two centuries, humans have become the planet’s dominant species, changing and often degrading Earth’s environments and living systems, including human cultures, in unprecedented ways. Contemporary worldviews that have severed ancient connections between people and the environments that shaped us – plus our consumption and population growth – deepened this degradation. Understanding, measuring, and managing today’s human environmental impacts – the most important consequence of which is the impoverishment of living systems – is humanity’s greatest challenge for the 21st century.

Explanation:

Cross-contamination of food occurs when a. perishable foods are kept at room temperature for more than 2 hours b. a utensil contaminated with a microorganism from a previously handled food contacts a second food c. two or more food handlers work on the same food d. two or more microorganisms grow in the same food

Answers

ANSWER: B

explanation: from what I learned in culinary arts, this is kind of a trick question. Its not asking how foods can get contaminated, its asking how CROSS CONTAMINATION can occur. Cross contamination occurs in three ways think of it like this: food-to-food, equipment-to-food, and people-to-food. The answer has to be between B and C. But the answer is B, because the utensil is already contaminated and it is coming in contact with another food. The two or more food handlers working on the same food are not bringing anything contaminated into the situation. Unless they are contaminated (by they I mean their hands lol) then it cross contaminates but that's not it lol im 99% sure the answer Is B.

Cross-contamination of food occurs when two or more foods come into contact with each other, transferring microorganisms from one food to another. This can happen in a number of ways, including direct contact, contact with a contaminated surface or utensil, contact with a contaminated food handler, or contact with airborne microorganisms.

What is the most common type of  cross-contamination ?

The most common type of cross-contamination is direct contact, which can occur when one food touches another. This is especially true of perishable foods, which should not be kept at room temperature for more than two hours.

If they are kept at room temperature longer than this, bacteria and other microorganisms can quickly multiply, potentially leading to cross-contamination.

Another common way for cross-contamination to occur is through contact with a contaminated surface or utensil. If a utensil that has been used to handle a food contaminated with microorganisms comes into contact with a second food, the microorganisms can transfer to the second food and cause cross-contamination.

Similarly, if two or more food handlers work on the same food, their hands can transfer microorganisms from one food to another, leading to cross-contamination. Finally, if two or more microorganisms grow in the same food, they can interact with each other and potentially cause cross-contamination.

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.

Answers

Answer:

Feathers initially evolved in a role associated with sexual selection.

Explanation:

In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

Answers

Answer:

is a thick band of neural fibers enabling communication between the two brain hemispheres.

Explanation:

A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.

The human brain consists of various sections and these includes;

I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.

II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making

III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.

The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.

Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen. Option A is the right answer.

What is photosynthesis?

Photosynthesis is the process by which green plants prepare their own nutrients with the help of sunlight, water, and carbon dioxide.

Photosynthesis helps plants to prepare their own food, these plans are called autographs.Photosynthesis takes place inside the protoplast.This process takes place in some other organisms other than green plants.Chlorophyll is the green pigment that is required for this process to take place.The end products that are formed in the process of photosynthesis are glucose and water.

Hence Option A is the right answer.

The flash patterns of fireflies attract mates of their own species. What type of reproductive isolation is this an example of?

Answers

Behavioral Isolation, Behavioral isolation occurs when the presence or absence of a specific behavior prevents reproduction from taking place. For example, male fireflies use specific light patterns to attract females. Various species display their lights differently; if a male of one species tried to attract the female of another, she would not recognize the light pattern and would not mate with the male.

which structures in plant cells build protein molecules under the control of the nucleus?
a) cell walls
b) chloroplasts
c)mitochondria
d) ribosomes

Answers

The cell walls, chloroplasts, and mitochondria play important roles in plant cells, they are not directly involved in building protein molecules under the control of the nucleus. D

Ribosomes are the structures in plant cells that build protein molecules under the control of the nucleus.

Ribosomes are tiny, complex molecular machines composed of RNA and protein molecules.

They are involved in the process of protein synthesis, where they facilitate the translation of genetic information from the DNA in the nucleus into functional proteins.

The nucleus of a cell contains the DNA, which serves as the blueprint for building proteins.

However, the actual synthesis of proteins occurs in the cytoplasm, outside the nucleus.

Ribosomes are responsible for this task.

Ribosomes can be found both freely floating in the cytoplasm and attached to the endoplasmic reticulum (ER).

The ones attached to the ER are called rough endoplasmic reticulum (rough ER) due to the presence of ribosomes on their surface.

These ribosomes associated with the rough ER are involved in the synthesis of proteins that are destined for secretion or for integration into the cell membrane.

The process of protein synthesis involves the decoding of the genetic information stored in messenger RNA (mRNA) by ribosomes.

Ribosomes read the mRNA sequence and assemble amino acids into a growing polypeptide chain, forming a functional protein.

Cell walls provide structural support, chloroplasts are responsible for photosynthesis, and mitochondria are involved in cellular respiration. However, the primary site for protein synthesis in plant cells is the ribosomes.

Therefore, the ribosomes (option d) are the structures in plant cells that build protein molecules under the control of the nucleus.

Answers

Answer:

skin acts as a protective barrier, therefore it does not secrete hormones

Skin does not secrete hormones. Thus, the correct option is B.

What are Hormones?

Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.

Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.

The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.

Therefore, the skin does not secrete hormones. Thus, the correct option is B.

An antibody molecule has a molecular weight of 150 kD when analyzed by SDS polyacrylamide-gel electrophoresis (SDS-PAGE). Treatment with mercaptoethanol, a reducing agent that breaks disulfide linkages, yields polypeptides with molecular weights of 50 kD and 25 kD, and both of these bands are similar in intensity and thickness. Based on this gel pattern as described, what can we conclude about the molecular composition of the antibody molecule

Answers

Answer:

The antibody has a molecular weight of 150 kD and consists of four subunits: two subunits of 50 kD and two subunits of 25 kD, which are bonded by covalent bonds.

Explanation:

Sodium dodecyl sulfate (SDS) is a detergent used to alter and denature proteins before gel electrophoresis. SDS can break hydrophobic interactions and hydrogen (H) bonds, but this detergent does not break down disulfide bonds, which is a type of covalent bond between two sulfur atoms. Moreover, mercaptoethanol is a reducing agent used to break disulfide bonds. In this case, it is expected that mercaptoethanol can break disulfide bonds between the four subunits of the mature antibody, thereby yielding two bands corresponding to the 50 kD and 25 kD bands (two subunits of 50 kD + two subunits of 25 kD = 150 kD).
