You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone. Make an argument that you are using a sustainable system of growing a renewable resource, and explain why it is beneficial (and more sustainable) to couple algae farming with fish farming than simply to farm fish independently.

Answers

Answer:

A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.

An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.

What is an integrated aquaculture system?

An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.

For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.

Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.

The kelps serve as food to fish while fish waste serve as manure for kelps.

Therefore, integrating fish farming and kelp farming is a form of a sustainable system.

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.

Which of the following does NOT secrete hormones?

A. Ovaries
B. Skin
C. Adrenals
D. Pancreas

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).

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:

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.

This organ stores the main metal ion that forms part
of the red blood cell. Which ion is this, and what
molecule is it a part of inside the red blood cell?

Answers

Answer:

a. Iron (Fe) ion

b. Haemoglobin

Explanation:

Red blood cells (RBC), also known as erythrocytes, are one of the cells found in the blood. Red blood cells are the major components of the blood involved with the transport of oxygen throughout the body. Red blood cells are able to do this because they contain proteinous molecules called HAEMOGLOBIN.

Haemoglobin is a molecule that contains hemic iron groups. Haemoglobin is composed of an IRON ION at the core of its structure, which binds to oxygen atom. Hence, according to this question, haemoglobin is a proteinous molecule that contains iron-binding heme groups in the red blood cells.

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.
