Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell's activities.

Explanation:

Hormones are secreted by glands and travel to their target oragan through bloodstream.

Individuals with genotype the IAIA or IAi have blood type A. The ones with IBIB or IBi have blood type B. Others  with IAIB have blood type AB, and those with ii have blood type O. Mother has phenotype A and father has phenotype B.

Genotype is the genetic representation of an individual.

A blood genotype indicates the genetic composition of the blood type of an individual.

Blood genotype represents the following phenotype:

Thus, according to the given scenario, the genotype of mother is IAIA and father is IBi, so the phenotypes will be A and B respectively.

Cycads are an group of vascular plants that are ancient and were prominent components of the world's flora. As the cycad should not be kept dry, leaving it outside the classroom during holiday and not watering properly was the main reason behind the loss of that cycad.

Cycads usually prefer warm, moist environments in full sun for survival. As some species are also adapted to dry arid areas, with less winter rainfall.

With respect to the soil, Cycads can tolerate most garden soils with the addition of compost and organic matter, till they are well-watered.

As the cycad was left in the classroom during the school holidays and was not watered and given compost properly, it was found dead.

Thus, watering and composting was the main reason behind the loss of that expensive cycad.

At sea level water occur in natural liquid form in seas, lakes, rivers, waterfall. Water can be salty or freshwater.

The layer of the atmosphere closest to the earth is the troposphere. This layer is where weather occurs. It starts at the surface of the earth and extends out to about 4- 12 miles. The temperature of the troposphere decreases with height. This layer is known as the lower atmosphere.

As the altitude increases water changes its form as on the mountains where temperature is very low, exist in snow form. As the more height increases, the water changes into water vapour. In stratosphere water changes into gaseous form called as clouds.

Explanation:

Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

what is responsible for pumping blood to the lungs?

The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
