The portion of a sperm cell that contains digestive enzymes for penetrating he egg is called the acrosome.
I hope this helps.
Answer: A. motion parallax
Explanation:
In the phenomenon of motion parallax, objects that are moving at certain speeds across a particular field of vision, would also appear to move at greater speeds if they’re closer to the observer. This remains true even if the object instead of the person is moving
. The phenomenon always arises whether or not the object is moving or that the observer is moving in a manner that is relative to the object’s motion. This is because of the distance the object moves in comparison to the proportion of the observers’ field of view that it traverses. Thus, motion parallax generally describes one’s perception of the position of an object with a three-dimensional space, based on sensing said objects at different positions.
Answer:
Fever.
Explanation:
If gram-negative bacteria contain a small amount of Endotoxin in the circulatory system can cause different types of infections such as inflammation, bleeding, hypertension, clotting, and fever.
Endotoxin is known as glycolipids, lipopolysaccharide (LPS) the most potent toxic molecule which is capable of causing lethal shock. It is present in the bacterial cell wall.
<span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant.
O is always ii
A is IAi (heterozygous) or IAIA (homozygous)
B is IBi (heterozygous) or IBIB (homozygous)
AB is always IAIB
Remember: You get one allele from each parent!
1. Father must be ii, mother must be ii, so all children must be ii.
2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother.
3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes.
4. Father is ii, mother is IAIB. Children can only be IAi or IBi.
5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB.
Example of Punnett square:
3. Father is type A, heterozygous, mother is type B, heterozygous
Father must be IAi (heterozygous)
Mother must be IBi (heterozygous)
_______IA ____ i
IB____ IBIA____IBi
i _____ IAi______ii
Sorry, that was difficult on here, hope it's understandable.
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case.
Hope that helps!</span>
