Adult giraffes eat about 75 pounds of food in a day. On average, an area can provide 450 pounds of food per day for giraffes. Based on this information only, what is the carrying capacity for adult giraffes in this area?
Answer:
6 giraffes
Explanation:
If an area can provide 450 pounds of food for the giraffes and the giraffes eat 75 pounds of food per day, you can divide:
450 by 75= 6
6 giraffes is the capacity for that area

Which level of organization is represented by the skeleton of the snake?
А.organ
B.organism
C.tissue system
D.organ system
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.

What are the two main principles of Mendelian genetics?
Answer:
The key principles of Mendelian inheritance are summed up by Mendel's three laws: the Law of Independent Assortment, Law of Dominance, and Law of Segregation
Explanation:
__________
Answer:
Mendel's observations from these experiments can be summarized in two principles: According to the principle of segregation, for any particular trait, the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. Which allele in a parent's pair of alleles is inherited is a matter of chance.

Which statement best explains the importance of enzymes lowering the activation energy necessary for reactions to take place?
a Reactions that require less energy to begin are able to occur more quickly.
b Reactions produce heat, causing the chemical bonds to become strong.
c Reactions are able to proceed slowly to maintain the metabolism of the cells.
d Reactions requiring less energy are able to produce less product.
Answer:
A
Explanation:
because a enzyme simply speeds up a reaction and only does that by pressure and stress not by doing chemical changes
The statement which best explains the importance of enzymes lowering the activation energy necessary for chemical reactions to take place is: A. Reactions that require less energy to begin are able to occur more quickly.
A chemical reaction can be defined as a chemical process which mainly involves the continuous transformation or rearrangement of the ionic, atomic or molecular structure of a chemical element through a break down and formation of chemical bonds, in order to produce a new chemical compound.
As a general rule, the activation energy of a chemical reaction must first of all be reached by its combining chemical elements (reactants) before it can start or begin.
An enzyme can be defined as a biological catalyst that is used to speed up (increase) or catalyze (accelerate) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).
Hence, a chemical reaction that only require less energy to begin (start) are able to occur more quickly before those that require high energy.
In conclusion, the activation energy of a chemical reaction should be lowered in order for it to occur or take place fast (quickly) enough over a short period of time.
