The allele H codes for LDL receptors that are needed to metabolize LDL. People who are HH have healthy levels of LDL, whereas th

ose who are hh have dangerous levels of cholesterol that often lead to heart attacks and death during childhood. Interestingly, those who are Hh have high levels of cholesterol and are at risk of a heart attack as a young adult, but if their cholesterol is managed, they will have a long life. This is an example of _______.

Answer:

incomplete dominance.

Explanation:

According to my research on studies conducted by various geneticists, I can say that based on the information provided within the question this is an example of incomplete dominance. This refers to partial inheritance of one allele for a certain trait which causes the formation of a third phenotype that triggers a physical trait that results in the combination of both alleles phenotype's.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

What process do the animals (and plants) in the<br> rainforest use oxygen for?
KiRa [710]

Answer:

<u>Animals and plants use oxygen for processing cellular respiration.</u>

Explanation:

Most of all organisms use oxygen to undergo cellular respiration with the help of the mitochondria that powers energy. Cellular respiration is needed to obtain energy for survival. As products of cellular respiration, ATP energy is created, and carbon dioxide + water is released from the organism. Thus, an ecosystem like a rainforest with animals and plants use oxygen for processing cellular respiration.

Purple sulfur bacteria and filamentous sulfur-oxidizers both A. accumulate sulfur as intracellular granules.B. fix nitrogen.C. p
aksik [14]

Answer:

Option A, accumulate sulfur as intracellular granules.

Explanation:

Purple sulfur bacteria  belong to the group of Proteobacteria. These probacterias are  anaerobic  in nature and yet are able to photosynthesise. They are usually found in  water environments  such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.

while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.

Hence, option A is correct.

Surface tension is the result of water molecules with strong force.
Oksi-84 [34.3K]

<u>Answer:</u>

<em>The surface tension of any liquid is due to the attraction between the inter molecular forces. </em>

<u>Explanation:</u>

Strong inter molecular forces of attraction produces strong surface tension. If the hydrogen bond between the molecules gets disrupted then the surface tension also decreases.

When a liquid drops onto the floor then it assumes a spherical shape because the surface tension is minimum when the liquid assumes the spherical shape. Water has high surface tension and is important to environment.

How do enzymes act as catalyst to speed up biological reactions
Alona [7]

Enzymes are biological catalysts. ... Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate.on:

Observe and record the seeds, roots, stems, leaves, flowers of mustard and maize plants and the difference in propertiesCheck it
mart [117]

Answer:

Maize is monocot and fibrous roots whereas mustard is dicot and tap roots system.

Explanation:

The main difference between maize plant and mustard plants is that Maize is a monocot plant means only one cotyledon in their seed whereas Mustard are dicot which means having two cotyledons. Maize plant has a fibrous root system whereas mustard plant has tap root system. The leaves pf maize plant have parallel venation while on the other hand, the leaves of mustard having reticulate venation. The seeds of maize is bigger in size as compared mustard seed.
