Answer:
A. Left Ventricle
Explanation:
The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Mateo and Tomás are identical twins. Mateo was raised by his father and mother, and Tomás was
accidentally placed with another family after a mix-up at the hospital. At the age of 15, the boys ran into
each other at a football game and noticed that they appeared to be mirror images of each other. After
genetic testing proved that they are twins, the families discussed some of the differences between the boys.
Mateo is very athletic and intelligent and excels in basketball, but he does not take school seriously and has
F's in all subjects. Tomás is also athletic and intelligent and excels in baseball, and he makes straight A's as
a result of his strict home life and study routine. Although they are identical twins, what do you think
accounts for the differences in the two boys' academic performance based on the research?

What's photosynthesis?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

Identify the error in the following statement: “Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert glucose and water into carbon dioxide and oxygen.”
A. “glucose” and “carbon dioxide” should be switched
B. No errors
C. “water” and “oxygen” should be switched
D. “chloroplasts” should be “mitochondria”
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 corpus callosum separates the brain into two halves. separates the brain into two halves. is a large network of neurons on the cerebral cortex. is a large network of neurons on the cerebral cortex. is a thick band of neural fibers enabling communication between the two brain hemispheres. is a thick band of neural fibers enabling communication between the two brain hemispheres. describes the hemispheres of the brain
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.
which structures in plant cells build protein molecules under the control of the nucleus?
a) cell walls
b) chloroplasts
c)mitochondria
d) ribosomes
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.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
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.

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 ________.
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.
