Answer:
The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today. 225 million years ago (Ma) India was a large island situated off the Australian coast and separated from Asia by the Tethys Ocean.

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.
What must be true about the person labeled "A"?
A. It is a male with at least one dominant allele.
B. It is a male with two dominant alleles.
C. It is a female with at least one dominant allele.
D. It is a female with two dominant alleles.
<h2><u>Answer:</u></h2>
Its a male with atleast one dominant allele.
Option A.
<h3><u>Explanation:</u></h3>
The gene for the attached earlobe is recessive while the gene for the free earlobes is dominant. In the phylogenetic tree, we can see that both the father and mother aren't having attached earlobes. So both of them are having atleast one dominant allele which makes them have free earlobe.
In the F1 offsprings, one of the female and a male is having free earlobes. So both of them have atleast one dominant allele. The 2nd female is having an attached earlobe. So both the recessive allele have come form one parent each. So both of them are heterozygous.
Thus, the male marked as A atleast have one dominant allele. He can be a homozygous dominant, but the probability is 25%.
Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
The independent variable would be temperature, the dependent variable would be planted height/number of leaves, and all other factors would be constant variables in an experiment to find the temperature at which beans sprout the quickest.
<h3>What would be the variables, If you were running an experiment to determine the temperature at which beans sprout the fastest?</h3>
- The independent variable would be temperature, the dependent variable would be planted height/number of leaves, and all other factors would be constant variables in an experiment to find the temperature at which beans sprout the quickest.
- The modified variable used in the study serves as the independent variable. Different planted beans would be exposed to various temperatures to discover the temperature at which they sprout the quickest. As a result, in this situation, the temperature is acting as the independent variable.
- The variable measured during the study whose value depends on the given controlled variable is known as the dependent variable. In this situation, the beans' growth would vary according to the temperature they are permitted to grow in. Thus, the dependent variable would be growth indicators like height, leaf count, etc.
- The variables that are maintained constant throughout all subject groups during the study process are known as controlled or constant variables. Conditions should be maintained constant for all participants, excluding the independent and dependent variables. These all fall under the category of controlled or constant variables.
