4. How do enzymes affect the speed of a chemical reaction?
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Cartilaginous fish have cartilage skeletons, while bonefish have a skeleton that mainly consists of bone.
Bonefish:
Their endoskeleton is completely bone.They have the previous opening of the tipThey can be freshwater or sea fishCartilaginous fish:
They are predominantly cartilated in their endoskeletonTheir exoskeleton is placoid (very small denticles coated with lots of sharp enamel)The mouth of these fish is located in the middleA student reads that deer mice that migrated to the hills of Nebraska originally had dark colored
coats. Over many years, due to a mutation, the coat color of the mice changed to a lighter color to
blend in easily with the sand. Which argument summarizes the mutation in deer mice?
a) It is a harmful mutation as it caused a change in the original coat color of mice.
b) It is a beneficial mutation as it helped the mice survive in their new surroundings.
C) It is a neutral mutation as the change in coat color did not affect any body functions in the
mice, and only helped the survival of the deer mice living in Nebraska.
d) It is a neutral mutation as only the deer mice living in Nebraska were affected, and all other
populations were unaffected.
The argument which summarizes the mutation in deer mice is It is a beneficial mutation as it helped the mice survive in their new surroundings.
What is mutation?A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health. Compared to what we typically see in science fiction movies, this is completely different.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings.
Therefore, The argument which summarizes the mutation in deer mice is It is a beneficial mutation as it helped the mice survive in their new surroundings.

d. Strong connective tissue that attaches muscle to bone
e. muscles that you cannot control
f. muscles that appear banded
g. muscles under your conscious control
Answer:
Options A , C , E
Hope it helps!!
Smooth muscle is one of the three types of muscles involved in controlling the movements inside your body organs and is involuntary. Thus, options a and e are correct.
What are smooth muscles?Smooth muscles are the non-striated muscle that lacks sarcomeres and striations and thus lacks bands. They are found through the internal body structures and have a variety of functions.
The smooth muscles can be found in the walls of the liver, intestines, pancreas, urinary tract, uterus, etc. but not in the heart. They also have a spindle shape that contains only one nucleus in it.
They are not under the control of the organisms and rather are controlled by the nervous system, skeletal system, chemicals, and hormones.
Therefore, the smooth muscles are involuntary muscles that control the internal structure. Options a and e are correct.

In the scenario above, Red hair (R) is dominant to blonde hair (r). If two parents are
heterozygous for red hair, what percentage of their offspring will have red hair and what
percentage will have blonde?
Answer:
75% of the offspring will have red hair and 25% will have blonde hair.
Explanation:
Since red is dominent but heterozygous it will be represented like Rr. Since both parents have that put it on a punnet square to get 75% red and 25% white.

What is Solar energy?
Solar energy is the radiant heat and light from the Sun that is captured by a variety of technologies, including solar architecture, solar thermal energy (including solar water heating), and solar power to produce electricity.
It is a crucial source of renewable energy, and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies are often classified as passive solar or active solar. Utilizing photovoltaic systems, concentrated solar electricity.
A building's orientation toward the Sun, the use of materials with favorable thermal mass or light-dispersing qualities, and the creation of naturally ventilated rooms are all examples of passive solar approaches.
