All animals, except for _____, develop as a protostome.a. sponges
b. mollusks
c. arthropods
d. echinoderms
e. vertebrates
f. chordates

Answers

Answer 1
Answer: Protostomes represent animals whose embryonic cells cleave in a spiral an the mouth opening develops before the anus. These animals do not always have a body cavity. Sponges, mollusks and arthropods are protostomes. Echnioderms, vertebrates and chordates are not protostomes, they are deuterostomes. Deuterostomes develop the anus before the mouth, cleave radial and have a true body cavity.
Answer 2
Answer:

Final answer:

All animals, except for echinoderms and chordates (including all vertebrates), develop as protostomes. This refers to the development pathway where the first opening in the embryo (the blastopore) becomes the mouth of the animal.

Explanation:

All animals, except for echinoderms and chordates, develop as a protostome. The term protostome refers to a developmental pathway in which the blastopore, or the opening of the central cavity of an embryo in the early stage of development, becomes the animal's mouth. Mollusks and arthropods, as well as many other animal groups, develop in this way. However, echinoderms (starfish, sea urchins, etc.) and chordates, that include all vertebrates, develop as deuterostomes, where the blastopore becomes the animal's anus. This is a distinct mode of animal development, separate from the protostome pathway.

Where is the moon when you are in a location experiencing a low tide?A. directly over head at your location
B. on the opposite side of the Earth from you
C. halfway between you and the opposite side of the earth
D. over the north pole or south pole

Answers

Answer:

C

Explanation:

The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.

CANT GET WRONG , ITS LIKE A WORK BANK BUT DONT KNOW WHAT ITS CALLED.In any family, the children may or may not look like their parents. They may or may not look like their siblings. That's because each one of us inherit half of our chromosomes from our mother and half from our father. What assortment of we get varies from child to child. Our chromosomes contain many genes, and each gene codes for a specific trait. The traits people see, like eye color hair color, or height, also depend on whether the gene is dominant or recessive. In this family, brown hair is dominant over red hair. It is very possible that these two parents could only have children with brown hair! It is also possible that their children all have red hair! Why? First, to inherit a recessive trait like red hair, you must have two genes for red hair color. Because one parent, the mother, has red hair we know the mother must have two genes for red hair. The father has brown hair. We know he must have at least one gene for brown hair but he also has one gene for red hair. What two genes will their children have? It's a matter of probability. Each child has a 100% chance of inheriting the red hair gene from their mother and a 50% chance of inheriting the red hair gene from dad. That means, all the children will have at least one gene for red hair! 1.Where do our chromosomes come from? (Twelve word phrase) 2.What codes for each specific trait?
