Answer:

lunula

Explanation:

The lunula is crescent-shaped whitish colored area of bed of the nail.

<u>It is present at end of the nail.The lunula is not actually white in color but only appears white when it is seen through nail.  </u>

<u>Outlining nail matrix, lunula is extremely delicate part of structure of the nail. If one damages lunula, nail will be deformed permanently.</u>  

It appears whitish in color because of the  stratum basale obscures that underlies blood vessels.

You decide to study two species of birds, both of which form monogamous pairs (one male and one female). In species 1, you find
TEA [102]

In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.

  • This is because the species 2 are having many eggs.
  • These eggs were formed due to fertilization with multiple male bird partners.
  • As a result we can expect eggs with different genotypes.

Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts

Select the correct statement(s):
expeople1 [14]

Answer:

The correct option is B <em>Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus</em>

Explanation:

a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.  

b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.

c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.  

d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.

Anna tries to keep her kilocalorie intake under control. She eats mostly lean meats or fish and a lot of vegetables. Yesterday,
n200080 [17]

Answer:

The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).

Explanation:

Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.

Here, Anna consumed  7 grams of fat (in salmon)

, 36 grams of carbohydrates (in sweet potatoes and asparagus)  and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.

Therefore, total calories in 7 grams of fat is 7*9=63 kilocalories.

Total calories in 36 grams of carbohydrates is 36*4=144 kilocalories.

Total calories in 27 grams of protein is 27*4=108 kilocalories.

Therefore, the total calories Anna consumed for dinner is 63+144+108=315 kilocalories i.e., 300 kcal.

The calories that came from proteins is 108 calories  i.e., 100 kcal.
