Answer:
promote stomatal closure during drought stress.
Explanation:
Abscisic acid inhibits the growth and stomatal opening, specifically when the plants are exposed to some stress conditions. Abscisic acid also regulates the seed maturation and seed dormancy. ABA concentration in leaves increases multiple folds under drought conditions. Its accumulation in leaves promotes closure of stomata and prevents the water loss by transpiration. ABA is required to restore the turgor pressure under drought conditions by stimulation of stomatal closure.
Scorpions are carnivores as they attack and paralyze their prey by stinging them with its tail. Depending on the scorpion's size, they eat from the smallest of insects like cockroaches and crickets to larger creatures like mice, small rabbits, and birds.
Answer:
From the whole progeny of 544 plants, 34 individuals are expected to have short stems and white flowers.
Explanation:
<u>Available data:</u>
- short stems coded for by recessive allele t
- white flowers coded for by recessive allele p
- T codes for tall stems
- P codes for purple flowers
- Cross between two heterozygous individuals
- Total number of the progeny 544
In a dihybrid cross, it is expected to get a phenotypic ratio of 9:3:3:1
Cross:
Parentals) TtPp x TtPp
Gametes) TP Tp tP tp

Punnett square)
TP Tp tP tp
TP TTPP TTPp TtPP TtPp

F1)
- 9/16 T-P-
- 3/16 T-pp
- 3/16 ttP-
- 1/16 ttpp
(<em>Note: The "-" symbol represents either a dominant allele or a recessive one</em>)
From these possible genotypes and phenotypes, we can get their corresponding amount of individuals
16 ---------- 544 individuals
9 ------------X = 306 individuals tall stems and purple flowers T-P-
3-------------X = 102 individuals with tall stems and white flowers T-pp
3------------ X = 102 individuals with short stems and purple flowers ttP-
1 ------------ X = 34 individuals with short stems and white flowers, ttpp
<span>It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside cell. Then It passes through the cell membrane and attaches itself to a receptor protein present in the cytoplasm.
It passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.</span>
Answer: Debido a la fuerza del tigre y el poder místico, la cultura china cree que el tigre tiene cualidades curativas únicas que pueden ayudar a tratar enfermedades crónicas, curar enfermedades graves y reponer la energía esencial del cuerpo. Debido a este motivo, los tigres están en peligro de extinción
Hope this helps (:
