True.
Shivering is a bodily function in response to cold in warm blooded animals/human. When the core body temperature drops shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements creating warmth by expending energy.
Answer:
See the answer below
Explanation:
Tigers and goldsih share the same phyllum because they both posses the basic characteristics of animals in the phyllum chordata. <em>These characteristics include;</em>
- <u>Possession of notochord</u>. The notochord is a rod-like structure that serves supportive functions and develops into the vertebral column in some group of chaordates.
- <u>Posession of post-anail tails</u> which is an extension of the posterior end of the of the body.
- <u>Possession of dorsal, hollow nerve chord</u> which eventually forms the brain and the central nervous system.
- <u>Possession of pharyngeal gill-slits</u>, an opening that develops into gill arches in golfishes and jaws in tigers.
Answer:
Man' s genotype= Bb
Children's genotype= Bb, Bb and bb for the three children
Explanation:
The gene involved here is that coding for eye color in humans. The allele for brown eyes (B) is dominant over that of blue eyes (b) i.e. brown eyes allele (B) will mask the expression blue eyes allele (b) in an heterozygous state.
A brown-eyed man is crossed with a blue-eyed woman (bb). The woman will be homozygous recessive since the recessive trait can only be expressed in a homologous state. They produce 2 brown-eyed offsprings and 1 blue-eyed offspring.
Note that, for the man who possess the dominant trait (brown eyes), he can either possess a homozygous or heterozygous genotype. Since he produced a recessive phenotyped (blue eyes) offspring when crossed with a blue-eyed woman, it means he donated a recessive allele (b) which combined with that of the woman. Hence, the man has a heterozygous genotype (Bb).
Having known the man's genotype, a cross (see attached image) between Bb and bb will produce four possible offsprings; 2 will be heterozygous brown-eyed (Bb) while the other two will be homozygous blue-eyed (bb).
Since two of their children were brown-eyed, they will have a (Bb) genotype while the blue-eyed child will have a (bb) genotype.
The correct answer for the question that is being presented above is this one: "penicillium and yeast." <span>Penicillium is a genus of ascomycetous fungi of major importance in the natural environment as well as food and drug production.</span>
G1 - synthesis of organell in cell
S - duplication of chromosome and replication of dna
G2 - ATP energy produced
