Answer:

carbohydrate for quick energy boost

protein to grow healthy hair

carbohydrate to race tomorrow

proteins to get bigger muscles

Explanation

carbohydrates contain glucose that can be broken down through glycolysis to provide energy in form of ATP. proteins are the main body building organic compounds. Keratin a type of protein is required for healthy hair growth. muscles also require proteins to get bigger.

During anaphase II in Meiosis, what major event takes place Question 26 options: Sister chromatids are pulled apart. Chromosome

baherus [9]

Answer:

The correct answer is A.) Sister chromatids are pulled apart.

Explanation:

This is because during Anaphase II in Meiosis, the sister chromatids are pulled apart.

Chromosome pairs line up during Prophase I. Not B. When the chromosome pairs pair up this is also Metaphase I. Not C. When chromosome pairs are pulled apart, Anaphase I is occurring.

Hope this helps,

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1

natulia [17]

Answer:

hyperpolarization
depolarization
hyperpolarization
depolarization
hyperpolarization
depolarization
depolarization

Explanation:

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. This is known as depolarization.

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. This is called repolarization.

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of hyperpolarization that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)

Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).

I hope you find this information useful and interesting! Good luck!

Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination

Salsk061 [2.6K]

Answer:

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.

Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.
