How have scientists determined the earth's core is composed of iron and nickel?
Sedaia [141]
<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or radioactive dating is used, for example, rocks or carbon, in which trace radioactive impurities were specifically fused when they were framed. The strategy looks at the abundance of a normally happening radioactive isotope inside the material to the abundance of its decay items, which shape at a known consistent rate of decay.</span>

Black fur in mice (
Tpy6a [65]
The answer is D) 1/2.

Let's imagine that two genes of the genotype can be analysed separately.

Black fur is determined by dominant allele B. In this case, parents Bb and BB will give offspring with only brown fur:
Parents:          Bb     x     BB 
Offspring:     BB   BB   Bb   Bb
Both homozygous (BB) and heterozygous (Bb) offspring will have black fur.

On the other hand, long tails are determined by recessive allele t. Parents Tt and tt will have 50% offspring with short tail and 50% offspring with long tail:
Parents:         Tt         x       tt
Offspring:    Tt      Tt        tt      tt
Heterozygous offspring (Tt) will have short tail, and homozygous offspring (tt) will have a long tail.

So, the offspring will definitely have black fur and will not affect the fraction of the offspring with black fur and long tails from the cross of <span>BbTt × BBtt. But, </span>there will be 2 out of 4 offspring with short tails which is 50% or 1/2.

Rina8888 [55]

Answer:

Plasma plays an essential role of transporting nutrients and waste.

Explanation:

The largest constituent of the blood that comprises 55 percent of its entire constituents is the plasma. It is a light yellow liquid, which along with water transports enzymes and salts to different parts of the body. Plasma primarily plays an essential role in transporting hormones, nutrients, and proteins to different body parts.  

Apart from this, plasma also carries waste materials withdrawn from the cells and discharges it out of the body.

How many calories are provided by a food that contains 29 grams of carbohydrate, 6 grams of protein, and 1 gram of fat?
Andrej [43]
Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal

According to the table above, we can calculate required value:

29x4 + 6x4  + 1x9= 149 kcal/g
