Why are reduction division and haploid gametes important?
Answer:
This is in order to maintain the species number of chromosomes.
Explanation:
Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.
Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .
During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.
Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.
The offspring produced between the mating of a tiger and a lion, a liger, which is unable to reproduce, is an example of which form of reproductive isolation?
a. temporal isolation
b. behavior isolation
c. hybrid infertility
d. gametic isolation
e. hybrid inviability
Final answer:
Ligers, offspring of a tiger and lion mating, exhibit hybrid infertility due to hybrid sterility, which is a type of postzygotic reproductive isolation preventing them from reproducing.
Explanation:
The offspring produced between the mating of a tiger and a lion, a liger, which is unable to reproduce, is an example of hybrid infertility. Specifically, this is a case of hybrid sterility, which is a form of reproductive isolation that occurs after fertilization, resulting in a hybrid that is not capable of reproducing. Thus, the correct answer is c. hybrid infertility.
One would expect to find this protein involved in the elongation of bacillus anthracis to form its typical shape
The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function.
Explanation:The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function. For example, in the process of biological nitrogen fixation, the carrier protein leghemoglobin binds with a very high affinity to its substrate oxygen at a specific region of the protein where the shape and amino acid sequence are appropriate. If the shape or chemical environment of the active site is altered, the substrate may not be able to bind as strongly or not bind at all. Thus, for the protein to be fully active, it must have the appropriate shape for its function.

Study the diagram, which represents the general equation for photosynthesis. What do the letters Y and Z represent?
Y - glucose
Z - oxygen
Y - glucose
Z - carbon dioxide
Y - carbon dioxide
Z - hydrogen
Y - carbon dioxide
Z - oxygen
Answer:
The correct answer is Y - glucose, Z - oxygen
Explanation:
In photosynthesis, plants- and also other organisms- take carbon dioxyde (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
carbon dioxide + water → glucose + oxygen
In the diagram, the equation is:
carbon dioxide + water + sunlight → glucose + oxygen
Answer:
The correct answer is A.
Explanation:
Y represents Glucose, a product of cellular respiration. Z represents Oxygen, which is also a product of cellular respiration.
(CO2 + Water + Sunlight = Glucose and Oxygen)

Most enzymes in living things are made up of
1. Carbohydrates
2. Lipids
3.Proteins
4. Nuclear acids
Someone please help me with this as soon as you can!
Answer:
3. Proteins
Explanation:
Enzymes are naturally occurring groups of organic substances of protein origin (they can be form by 62 amino acid residues, such as 4-oxalocrotonate tautomerase enzyme monomer to 2500 residue size) with intra or extracellular activity that have catalyst functions. This is achieved by lowering the activation energy to allow a chemical reaction, resulting in an increased reaction speed and allowing the metabolism of living things. Importantly, although most enzymes are proteins, there are also enzymes consisting of RNA as ribozymes.

Trace the flow of energy by numbering the following events from start to finish. 1. Step 1 The Sun emits energy. 2. Step 2 A rabbit eats the plants and uses the energy for growth and respiration. 3. Step 3 Plants absorb energy from the Sun and use it for photosynthesis. 4. Step 4 A fox eats the rabbit and uses the energy for growth and respiration. 5. Step 5 The fox dies and is decomposed.
In an ecosystem, the energy flows from the producer to consumer levels. The plants utilise the energy from the sun and convert it into chemical energy. The chemical energy is stored as a form of energy molecules in the plants. The primary consumers eat the plants and get the chemical energy. The tertiary consumers eat the primary consumers and obtain energy from them. The dead organism is decomposed and the organic nutrients are restored in the soil.
Hence, the correct sequence would be:
1. The Sun emits energy.
2. Plants absorb energy from the Sun and use it for photosynthesis.
3. A rabbit eats the plants and uses the energy for growth and respiration.
4. A fox eats the rabbit and uses the energy for growth and respiration.
5. The fox dies and is decomposed.

The atp synthase uses this gradient to restore adp back to atp. what is this process called?
ATP synthase uses a proton gradient to restore ADP to ATP in a process known as chemiosmosis, which takes place during oxidative phosphorylation.
Explanation:The process by which ATP synthase uses a proton gradient to restore ADP back to ATP is called chemiosmosis. This occurs during oxidative phosphorylation, a key part of cellular respiration where the energy stored in the electrochemical gradient, developed due to the movement of protons (H+), is utilized. As protons flow through ATP synthase, much like water flowing through a turbine, they provide the energy needed for the enzyme to catalyze the production of ATP from ADP and inorganic phosphate (Pi).
The structure of hair is formed by keratin. Keratin is most likely which of the following polymers?
Answer:
Keratin is a protein.
Explanation:
Keratin is a fibrous protein that has the characteristics of rigid conformation, elasticity and impermeability to water. It has animal origin and is found in the vertebrate epidermis and in some epidermal appendages, such as hair, nails, hooves, feathers and scales. This protein is produced in cells called keratinocytes, which are the most abundant in the human epidermis.
Like any protein, keratin is made up of amino acids. It has a large amount of cysteine residues, which is responsible for 7% to 20% of the total amino acids present in keratin. Note that cysteine is mainly located in the terminal region of the keratin chains.
