Answer:

The answer is C.

Explanation:

When you breathe out or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.

Westkost [7]
So 6 were born that year, 5 emigrated, 3 died, and 1 immigrated. So +6, +5, -3, and -1. So 11 - 4. That would be 7. So there is 7 deer. You can determine from this information that there are 7 deer.

djverab [1.8K]

Complete question: While taking a walk in a park, Muskaan observed an insect on a pitcher plant (Nepenthes). Immediately the flower opened up and the insect slid down. To which of the following categories does the pitcher plant belongs?

a) Saprophytes

b) Insectivorous

c) Parasite

d) Symbiotic

Answer:

The correct answer is option b. Insectivorous

Explanation:

A carnivorous or insectivorous plant is the one that obtains most of its nutritional necessities from the capture and consumption of protozoans or animals, especially insects and arthropods.

These insectivorous plants grow in poorly nutritional soil, so they need to get nutrients from their prey. These species attract and trap their prey, and by the action of specific enzymes and digestive bacterias, they can absorb the insects' nutrients.

These insectivorous plants make use of their flowers to trap the prey. These tramp flowers are cup-shaped, and at the bottom of this cup, there is a liquid where insects get trapped and die.

Insects are attracted by aromas produced by the edges of the trap and when they land, they slip and fall inside, and once drowned, the enzymes digest them.

LUCKY_DIMON [66]

Answer: 4/16 yellow Labradors, 9/16 black Labradors and 3/16 brown Labradors.

Explanation: Two dihybrids would have BbEe alleles. Using Mendel's chess table of independent segregation to show the offspring,  we have the following results:

BBee - 1/16 - yellow

BBEe - 2/16 - black

BBEE - 1/16 - black

BbEe - 4/16 - black

Bbee - 2/16 - yellow

BbEE - 2/16 - black

bbEe - 2/16 - brown

bbEE - 1/16 - brown

bbee - 1/16 - yellow

If the offspring presents B_E_ phenotypes, it will have black pigment deposition. If the offspring presents bbE_ phenotypes, it will have brown pigment deposition. Otherwise, if it presents _ _ee phenotypes, there won't be any pigment deposition, therefore they are yellow.

Adding up all the phenotypes ratios, we have <u>4/16 yellow Labradors, 9/16 black Labradors and 3/16 brown Labradors</u>.
