They are composed of actin, troponin, tropomyosin, and myosin
<h2>Angiosperms </h2>
Explanation:
Angiosperms are the most diverse group of plants, some statements which reflect angiosperm adaptations to life on land:
- Flowers attract animal pollinators carrying pollen from other plants of the same species
- Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits
- In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators
- Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation
- Seeds protect and nourish plant embryos, and fruits protect the seeds
- Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals
Answer:
The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.
Explanation:
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:
p + q = 1
r-6 + R = 1
0.2 + 0.8 = 1
Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64
The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04
And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32
Answer:Transcranial Magnetic Stimulation (TMS)
Explanation:
Transcranial magnetic stimulation also known as repetitive transcranial magnetic stimulation. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. In TMS, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head that temporarily inactivates neural circuits. TMS devices operate completely outside of the body and affect central nervous system activity by applying powerful magnetic fields to specific areas of the brain that we know are involved in depression.
