In gymnosperms the cone is the female reproductive part and the pollen is the male reproductive part. Pine trees and other gymnosperms produce two types of cones. The male cone is called the pollen cone. ... A single tree usually produces both pollen and seed cones.
The range of 60 to 85 mmHg (millimetres of mercury) is the standard for normal
diastolic blood pressure. Blood pressure is the pressure of circulating blood on the walls of arteries and it is expressed with systolic and diastolic blood pressure. Systolic pressure is the one during the contraction of heart muscle and diastolic refers to the one when your heart muscle is between beats (minimum in between two heartbeats). For example, normal blood pressure in an adult is approximately 120/80 mm Hg. 120 mmHg is systolic, and 80 mmHg diastolic pressure.

The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

Answer:
it is one of newton's law it states that when two bodies interact, they apply forces to one another that are equal in magnitude but in opposite directions
Answer:
A) 300
B) 3:1
C) 9 long yellow : 3 long green : 3 short yellow : 1 short green
Explanation:
Long stems (L_) are dominant to short stems (ll)
Yellow seeds (Y_) are dominant to green seeds (yy)
We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.
C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:
- 9/16 L_Y_ (Long, yellow)
- 3/16 L_yy (Long, green)
- 3/16 llY_ (short, yellow)
- 1/16 llyy (short, green)
A) 3/16 × 1600 = 300 plants will be long and green.
B)
9/16 + 3/16 = 12/16= 3/4 plants will be yellow;
3/16 + 1/16 = 4/16= 1/4 plants will be green.
The ratio will be 3 yellow : 1 green
