Sexual reproduction increases the genetic variation of a species because:
Answer:
Sexual reproduction increases the genetic variation of a species because it involves combining of genetic materials of two parents/individuals to form an offspring.
Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.

Answer:
Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.
Explanation:
Cause:- (Exact cause of inflammation is not known)
But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.Types of tissues attack:-
Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.Result of immune system attack:-
Damaged myelin sheath stop forming whIte matter of central nervous system.Hence disrupt coordinating communication between different brain regions.Signs and symptoms:- vary from person to person
Diminished eyesight.Disrupt motor coordination.Weak sensory perception.Fatigue and dizziness.Speech disorder.Muscle weakness and spasticity.Difficulty in urination and stool.Diagnosis and treatment:-

Two insects groups vary genetically by two genes. When put together, they were able to reproduce a produce offspring that could also breed. Which best describes this insect population?
Answer:
The insects belong to the same species
Answer:
The insects are the same species perhaps.
Explanation:
The amino acids in the original partial sequence (N-term-...P-I-E...-C-term) have little to no impact on protein structure and function. However the amino acid sequence near the C-terminal end of the protein is required for normal function. Any amino acid changes in this region of the protein will result in a nonfunctional protein. Given this information, which reversion mutation in the gene would restore the normal function of the protein

Brad is swimming in the ocean on a hot sunny day. he finds the water to be much colder than the sand on the beach, even though the sun is warming them both. identify the reasons for brad’s observation. the water is colder than the sand because it requires more to change temperature. this is because the water has a higher than the sand.
Answer:
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up. The sand has a lower SHC so it requires less energy to heat up therefore heats faster and Brad will observe the sand to be hotter than the sea
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up.
What do you mean by specific heat capacity?The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
In thermodynamics, the specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity.
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.
