ae44f8a148c445248498b3dfa44a8269 Which analysisBEST describes the probability of an offspring having or not having sickle cell disease, and carrying or not carrying the defective gene for sickle cell disease?
Answer: I think this is the answer, Sickle cell can only be passed on from parents to children. It is not contagious and it cannot skip a generation. The likelihood of having it depends on how many SC genes one or both parents have.

Amino acids have similar structures. What part of an amino acid's molecular formula distinguishes the macromolecule from other amino acids?
O the R-group
o the amino group
o the carboxyl group
O the nitrogenous base W
Answer:
The R-group
Explanation:
Amino acids are organic compounds that combine to form proteins. There are 20 of them, out of which 9 are essential. All of them have a similar structure: they consist of an alpha (α) carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and an R group. The R group is the organic component, a side chain, that is unique to each amino acid.
This is why the first option is the correct one.
Answer:
the R-group

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.
Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

2. Once the solution across a membrane does in fact reach equilibrium, the molecules in solution will
A. move across the membrane to the outside of the cell.
B. completely stop moving across the membrane.
C. continue to move across the membrane in both directions.
D. move across the membrane to the inside of the cell.
Answer:
B
Explanation:
Molecules and ions diffuse through cell membrane due to a concentration gradient. But, once the equilibrium is achieved between inside and outside the cell, molecules stop moving. Thus, option B is correct.
What is cell membrane?Cell membrane is an organelle surrounding the cell which facilitates the transportation of ions and molecules, inside and outside the cell. To maintain an ionic balance is important in metabolism of living things.
Ions such as sodium and potassium are balanced by a mechanism called sodium -potassium pump. The sodium ions outside the cell is greater than that of inside.
Similarly calcium pump works for calcium and magnesium. The concentration gradient of these ions make this flow of ions across cell membrane. Hence, once they achieve equilibrium the flow will stop and no ions will be transported across the membrane.

How do molecules in the cells of the body release energy
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation.
Through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.
How do cells release energy?All cells have energy to do work whereas glucose and other sugars have cell food. Almost all of these contain a source of energy for cell activities. When glucose is stored as glycogen or taken up as starch, it must be broken down into individual molecules before cells are able to to use it.
Chemical energy is stored in the bonds of sugars. When these bonds of a sugar molecule are broken, there is an explosion of energy which can be used by the cell.
These cells can release energy in two basic processes which are cellular respiration and fermentation. Oxygen is needed for cellular respiration, but not for fermentation. Furthermore, cellular respiration releases a lot of usable energy compared to fermentation.
Thus, through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.

How would you compare a circle to an ellipse?
Answer:
A circle is a closed curved shape that is flat. ... Instead of having all points the same distance from the center point, though, an ellipse is shaped so that when you add together the distances from two points inside the ellipse (called the foci) they always add up to the same number.

Explanation:
Two students were having a discussion about viruses.
Student A believes viruses are not living organisms .
Student B believes viruses are living organisms.
Which student is correct and why?
Student A is RIGHT because viruses are not living organisms.
All living organisms are composed of cells, and viruses do not have cells (they only have protein coats that protect their genetic material).Viruses are entities that need to parasite the cells of different host organisms to survive.In consequence, a virus cannot replicate in absence of a suitable host cell.In conclusion, student A is RIGHT because viruses are not living organisms.

Does adding or taking away a proton change the identity of the element? Yes or no
Answer:
yes
Explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
Answer:
Yes
Explanation:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

What structure do plant cells have during cytokinesis that animal cells do not have?
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.
