Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.

A: 90
B: 10
C: 100
D: 45​

Answers

Answer: A

Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Which of the following explains how rumen biotechnology improves feed for ruminant animals?
by identifying small amounts of bacteria from tiny samples of meat
by boosting the bioavailability of carbohydrates and protein in plants
O by helping animals grow larger more quickly and produce cleaner meat
O by screening animals for physical defects and certain diseases

Answers

Rumen biotechnology improves feed for ruminant animals by boosting the bioavailability of carbohydrates and protein in plants. It can be used to improve the nutritive value of ruminant feedstuffs.

Rumen biotechnology refers to the use and management of the techniques of forestomach fermentation in order to improve the efficiency of ruminant production.

Rumen biotechnology can be used to improve the amount as well as the availability of macronutrients (i.e., carbohydrates and proteins) in plants.

However, this technology (rumen biotechnology) exhibits several limitations mainly associated with the identification of bacterial strains used during inoculation, proteins (recombinant enzymes) and genomic stability of the genetic constructs.

Osteoporosis is more prevalent among women than men because women generally
have more bones in their bodies than men have.
take in more calcium than men take in.
have lower bone mass than men have.
exercise more than men do

Answers

Answer:

Have lower bone mass than men have

Explanation:

Osteoporosis is a bone thinning disease that is more prevalent among women than men and typically occurs after 50. The reason women are more likely to get the disease than men is because after 50 many women have gone through or are going through menopause. Menopause causes the ovaries to produce less estrogen which is what had previously been promoting bone density.

The other answers are incorrect because...

A: have more bones in their bodies than men have: for the most part everyone has the same amount of bone in there body (although there are diseases that cause a persons bones to fuse together making them have fewer bones than the average person)

B: take in more calcium then men take in: more calcium would actually cause someone to be less likely to get osteoporosis because it strengthens the bones.

C: exercise more than men do: Osteoporosis is more common in malnourished women and women who do not get regular physical activity to strengthens there bones. So getting more exercise would actually lessen the chance of getting osteoporosis.

B) the new plant formed from as reproduction

D) The new plant is genetically identical to the original plant.

The new plant grows vegetatively from the cutting and will look exactly like the original plant.

Vegetative propagation

Cutting is a form of vegetative propagation attribute of some organisms.

Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.

Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.

Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is incorrect, state the length of b. Explain your answer in complete sentences. Use vocabulary such as Pythagorean Theorem, side, hypotenuse, square root etc.

Answers

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.
