Hey there Brainly peep!
They can respond to changes in their environment which the answer is
D. Mollusks and arthropods can respond to changes in their environment, while jellyfish and sponges cannot.
Hope this helped
Factors such as age, gender, family history, and genetics are <u>nonmodifiable</u><u /> risk factors, while <u>modifiable</u><u /> risk factors are ones that are in your power to change.
You cannot change your age, family history or genetics - you will age no matter what, and you will inherit some traits from your ancestors whether you like it or not. Gender is more flexible nowadays as there are surgeries that can help people change their gender.
Answer:
smooth endoplasmic reticulum
Explanation:
Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.
Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.
Our star—the Sun—is a bubbling, boiling ball of fire. See Picture 1 to the right. It constantly belches out great clouds of hot gas. This gas is all charged up with electricity, too. This stuff travels at astounding speeds, some of it right toward Earth! This means that Earth’s weather happens inside the Sun’s weather!
Thank goodness Earth’s magnetic field (see Picture 2) and atmosphere protect us from most of this blast. Otherwise, the Sun’s weather would be OUR weather. Yikes!
However, we are still affected by the Sun’s atmosphere and its violent activities. We call this part of our weather “space weather,” because it comes to us through space from the Sun.
A person whose red blood cells agglutinate with anti-B antibodies BUT NOT anti-A antibodies is type AB.
<h3>What is an agglutinate?</h3>
Agglutination is the process by which specific antibodies to antigenic components on the surface of red blood cells or inert particles (direct agglutination) or to antigenic components adsorbed or chemically attached to red blood cells or inert particles produce clumps of cells or inert particles (passive hemagglutination and passive agglutination, respectively).
When antibodies on one RBC attach to the antigen on another RBC, a process known as agglutination, globular to amorphous, grape-like aggregates of RBCs are formed. RBC agglutination supports immune-mediated hemolytic anemia when it is present (IMHA). The majority of IMHA instances do not exhibit agglutination, but when it does, immunoglobulin M (IgM) is the most frequently implicated because of its pentavalent nature. Agglutination, however, might be brought on by a very thick IgG antibody coating of the RBC membranes. Agglutination is typically regarded as IMHA's diagnostic sign.
