Blood passes from the right ventricle to the <u>Pulmonary valve </u>and then the <u>Pulmonary artery</u> before reaching the lungs to pick up oxygen
<h3>Blood circulation procedure </h3>
When the blood enters the right ventricle it contracts and sends the blood through the Pulmonary valve before it reaches the Pulmonary artery which is passes the blood to the Lungs where it becomes oxygenated.
Hence we can conclude that Blood passes from the right ventricle to the <u>Pulmonary valve </u>and then the <u>Pulmonary artery</u> before reaching the lungs to pick up oxygen.

Answer:
Explanation:
Gametes are able to survive extensive heat and radiation. The gametes have storage tissue that supply nutrients needed, sustain growth and protective coat this hardened tissue prevent dessication i.e dryness through loss of water and maintain its water level. Abscissic acid helps keep the plant in shape if desssication occur. Ability to regulate fluid helps maintain heat.
d. disperse offspring through both time and space, seeds are disperse via diverse means such as insect, wind, mechanical transport. The protective covering on the seeds help them to last longer and protect damage to the cells till they get a favourable condition to establish and grow. Hence offspring can be disperse in space and time.
Seeds contains endosperm which are food reserves for developing embryo. In seeds adequate nutrients required for growth are supplied for gamete to survive
Alteration of generation occur in plant where a multicellular gametophyte that has n chromosome i.e haploid chromosome will alternates with
A diploid sporophyte with 2n chromosome this two then fuse to products a gametes.
Hence, A,B,D,E are correct
but c. hydrodynamic locomotive forces and variable gametophyte generation is not correct because Locomotive forces and variable gametophytic generation in seed plants do not often occur. Gametophytes produces pollen and embryo sacs.
Answer:
False
Explanation:
A reference provides a haploid mosaic of different DNA sequences from each donor.
The sun's endothermic or exothermic energy has a different, but distinct actions with Earth, which makes them suitable for each other. With the sun's endothermic energy, Photosynthesis occurs in plants, it helps plants absorb heat energy from the sunlight, which lets the plants convert carbon into oxygen and glucose. While the exothermic energy, causes rain. It lets the condensation process of water vapor release energy in the form of heat, which causes rainfall.
D- species
A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
