The diagram above shows the process of meiosis. The segregation that occurs during meiosis results in a -
a. group of genetically identical cells
b. single fertilized egg cell
c. decrease in the number of cells per organism
d. reduction in the number of chromosomes per cell
Answers
Answer:
Its D not b reductions in the number of chromosomes per cell
Explanation:
The segregation that occurs during meiosis as illustrated in the diagram above results in a reduction in the number of chromosomes per cell.
What is meiosis?Meiosis is the division process that results in the formation of daughter cells that are genetically different from one another.
According to this question, the meiotic process is depicted in the diagram above. Four daughter cells are produced as a result of the division process.
However, each daughter cell contains half the number of chromosomes as the parent cell, hence, there is a reduction in the number of chromosomes per cell.

Describe the following types of cell signaling:
Autocrine:
Juxtacrine:
Endocrine:
Paracrine:
Answers
Answer:
Autocrine = Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Juxtacrine = Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.
Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.
Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.

Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answers
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

In an experiment, a scientist isolates mitochondria from living cells and suspends them in two different buffered solutions. One solution is maintained at pH 4, while the other solution is maintained at pH 9. The
scientist finds that mitochondria in the solution at pH 4 continue to produce ATP but those in the pH 9 solution do not
The results of the experiment can be used as evidence in support of which of the following scientific claims about mitochondrial activity?
Mitochondria in a cell free environment are unable to convert thermal energy into ATP.
The electron transport chain pumps electrons from the cytosol to the mitochondrial matrix,
CATP production in mitochondria requires a hydrogen ſon gradient that favors movement of protons into the mitochondrial matrix.
D
ATP synthase molecules change their orientation in relation to the proton gradient across the mitochondrial membrane.
Answers
Answer:C
Explanation:
The scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
Cellular respiration is defined as a group of metabolic reactions by which cells can generate ATP (the energy coin of the cell), by using oxygen and the energy released in the chemical bonds of foods (e.g., glucose).Cellular respiration has three main types of reactions: glycolysis, the acid citric cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and oxidative phosphorylation occur in the mitochondria.During oxidative phosphorylation, the movement of electrons through a series of carriers is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.Subsequently, this proton (H+) gradient is then used to generate ATP by using an ATP synthase.In conclusion, the scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).

The fossil record is incomplete and does not contain all of the Earth's past organisms. Why have some organisms been found as fossils while others have not?
A. Fossils only exist for organisms that lived over 3 million years ago.
B. Fossils only exist for organisms that had shells or hard outer body coverings.
C. Only very large organisms have enough body mass to result in fossil formation.
D. Most organisms die and decompose without leaving any fossil remains.
Answers
Answer:
The answer is D.
Explanation:
We can easily knock out answer choice A, as fossils only take around 10,000 years to form completely. Not just for the organisms that lived 3 million years ago. Answer B as well, since theres been fossils for about just every animal out there. Answer C, we have seen the tiniest of organisms turn into fossils before, so this is outright wrong. Answer D, is correct. Why? Because fossils need the PERFECT conditions to be properly made. We´ve all seen a dead cat on the road or two. Everytime we visit, we notice how slowly more and more deterioated the body gets. Until theres nothing but maybe the skull and some other few spare bones left.

Answer:
Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.

atoms, yet 65% of a typical organism's mass is
oxygen
І
Answers
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

Body waves and Surface waves
Body waves are propagated through a material
Surface waves moves through the surface
Primary waves:
They are called P-waves or primary waves These waves have the fastest velocity of all types of seismic waves - 5 to 8km/sThey can pass through any materials because they are longitudinal waves. They are also called compressional wavesSecondary waves:
These are s-waves or shear waves and are body wavesThey have a velocity of about 1-5km/s These waves are transverse wavesThey cannot pass through a region made up of fluidsLove waves
They are transverse wavesThese waves are surface wavesThey move horizontally on the surfaceLove waves cannot pass through liquidsRayleigh waves
