How is it possible for a baby to grow all of its organs

Biology
1 answer:
avanturin [10]3 years ago
5 0

Explanation:

during the embryonic stage the baby grows its organs

Nervous system. This is one of the first things that develop. It includes the formation of the baby’s brain, spinal cord, and nerves.

Heart. An S-shaped tube forms on the front of the embryo. This will become the baby’s heart. At first the heart does not beat, but soon it starts beating and pumping an early form of blood.

Face. The baby’s facial features begin to take shape. The eyes and ears form. The eyes move forward on the face, and eyelids form. Pieces of tissue grow and join together to create the forehead, nose, cheeks, lips, and jaw. The nasal passages, mouth, and tooth buds form the baby’s first teeth. A tongue with taste buds also forms.

Arms and legs. At first, the baby’s arms and legs begin as little buds that sprout from the embryo’s sides. As they grow, the arms look like paddles and the legs look like flippers. A ridge appears on the end of each one. They eventually become the baby’s fingers and toes.

Sexual organs. Cells form to become the baby’s eggs or sperm. The baby’s private parts (girl/boy) is visible at the end of the embryonic period.

Muscles and movement. Muscles develop and the embryo begins to move. At first it’s only twitching and reacting to touch. Once the nerves and muscles start working together, the baby can start moving on purpose.

I need some help
Elan Coil [88]

Answer:

0%

Explanation:

It was a little hard to see your cross, so I made another one and it is attached below.

So what you are looking for is the likelihood of an offspring with a phenotype of brown spots and short tails.

Without using the Punnet, we can already deduce that it is 0%. This is because brown spots are recessive, and the only way a brown spotted dog would have this trait, is each parent had at least 1 recessive allele for this trait.

So the expected genotype for brown spot would be:

bb

Only one of them has this, so they cannot have brown spots.

Which group of invertebrates is most closely related to vertebrates?
MissTica

Answer:

cephalochordates

Explanation:

Cephalochordata is one of the subphylos of the phylum Chordata with about 30 species. Cephalocords are small (centimeter long) animals, thin, laterally flattened (like the body of fish), transparent and live buried in sandy substrates leaving only their heads apparent. They are currently represented by the amphioxes. Cephalocords are the group of invertebrates that is most related to vertebrates.

The body of the cephalocordates is composed of longitudinal (horizontal) muscles that are divided by blocks called myotomes. The notochord holds in adults giving a stronger structure to the body.

Meat tenderizer contains an enzyme that interacts with meat. If meat is coated with tenderizer and then placed in a refrigerator
nevsk [136]

Answer:

The enzyme would be deactivated.

Explanation:

Enzymes are usually deactivated by low temperatures.

<em>Enzymes are proteinous in nature, function by catalyzing biological reactions, and have a particular range of temperatures where they function optimally. Above these temperatures, the catalyzing attribute of enzymes gradually declines till they are denatured by high temperature and below the optimal temperature, their catalyzing attributes also decline. However, instead of being denatured by very low temperatures, they become deactivated instead.</em>
