Answer:
<h2>
Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>
Explanation:
The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.
<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>
<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>
Answer:
100%
Explanation:
Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:
YY x yy
Yy Yy Yy Yy
All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.
<em>Hence, the percentage of the offspring that will have a yellow flower would be </em><em>100%.</em>
Answer:
The body uses sugars from carbohydrates which supply the brain with glucose as the brain uses it as a "fuel source".
<h2>Why is glucose so important for the brain?</h2>
Quick answer: It takes a lot of energy to receive, interpret, and send signals via your neurons. Glucose is the simples sugar that can be used to make energy.
Cells require energy to carry out their typical everyday tasks. The simplest sugar that our cells can utilize for energy is glucose. Since your neurons are specialized cells, many additional cells are also present to support or protect them. All of the senses you can experience utilizing incoming neurons (from the body to the brain) are transmitted to and interpreted by the brain, including touch, pain, vibration, temperature, smell, sight, hearing, taste, and others. Signal reception and interpretation need energy. Additionally, your brain instructs your body to "do" things, which uses energy. Additionally, you spend a significant portion of your waking hours "thinking," which consumes energy. This explains why 20% of the glucose in your body is used by our teeny, tiny, little brains.

Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.
Anaemia is defined as the decrease or the reduction of the oxygen carrying content of the blood which are the red blood cells.
These red blood cells and other blood cells which include the white blood cells and the platelets are produced in the body by the bone marrows by a process called haemopoiesis.
The bone marrow is divided into two:
- yellow bone marrow and
- red bone marrow.
The red bone marrow is made up of stem cells which can be converted to red cells when the need arises while yellow bone marrow is made up of fat.
During health conditions such as anaemia, there is increase in the need of red blood cells by the body.
There is usually the conversation of yellow bone marrow to red bone marrow to compensate for the increased demand of red blood cells.
This conversation is called an adaptive conversation.
Therefore,Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.
