According to Mendel's Law of Inheritance, one copy of a gene is passed randomly from each parent to their offspring. This is why gametes have half the usual number of chromosomes

The law of assortment states that different genes are not connected. In other words, the gene for eye color is not influenced by, nor does it influence, the gene for hair color. This allows gametes to form with a random mixture of traits.

The cell division that creates gametes according to these principles is known as meiosis. 

Explanation:

Gregor plant scientist, through his work on pea plants, discovered the elemental laws of inheritance.

He deduced that genes are available in pairs and area unit heritable as distinct units, one from every parent. Plant scientist half-tracked the segregation of parental genes and their look within the offspring as dominant or recessive traits.

The Principle of freelance Assortment describes however completely different genes severally cut loose each other once generative cells develop. The freelance assortment of genes and their corresponding traits was initially ascertained.

Where dose mass of a willow tree come from
MA_775_DIABLO [31]

Answer:

So where does the mass come from? The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Alex is participating in a 50 meter dash. Predict the most important chemical process his muscles will rely on during this race.
natta225 [31]

Answer: The correct answer to the question is option E

BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.

Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.

Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.

These chemical processes are explained below;

Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.

Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.

Scientists discovered a new species of freshwater fish that lives in a pond with a very low O2 level. When they measured the oxy
AysviL [449]

Answer:

In order to propose a hypothesis, there is a need to first see the function of gills in fishes. The gills of fishes comprise blood vessels that exhibit inherited tendencies of getting oxygen out of the water, which was consumed by fishes from their mouths. These gills also comprise thin walls, and when water moves over these walls of blood vessels, the oxygen from water moves into the blood, and then this oxygen-enriched blood goes to various organs.  

Thus, one of the hypotheses in the given case, can be the number of blood vessels, which are found in the gills of the mentioned freshwater fish to be higher in comparison to the blood vessels found in the normal fishes, and apart from this, the surface area of the thin walls, which are found in the gills is also more in the new species of freshwater fish.

For patients who have familial hypercholesterolemia, what should be the focus of teaching for blood cholesterol reduction
Brut [27]
<span>Taking lipid lowering drug as perscribed is the focus. Hypercholesterlmia is a condition where LDL is greater in the blood. So the level of such lipids should be lowered. Inactivity, obesity and unhealthy diet are causes. So the treatement should involve avoiding the situations leading to high LDL.</span>
