How do the plates and Mantle interact at each type of plate boundary
Wewaii [24]

Answer:

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. ... At convergent boundaries, plates collide with one another.

Which nutrition tip would you not recommend?
Julli [10]

Answer:

b. It is recommended to go long periods of time without eating to loose weight.

Explanation:

Spending long periods of time without eating is not the right thing to do when you want to lose weight. Spending too much time fasting does not guarantee weight loss, and causes serious illnesses that threaten, among other things, the heart.

A recent survey by nutritionist Roberta Cassani of the Institute of Nutrition in Itu, São Paulo state, shows that the greater the number of hours without putting anything in the mouth, does not help anyone lose weight, on the contrary, fasting causes the increase of the circumference of the abdomen.

According to the scientist, the main reason that prolonged fasting is an enemy of the waist is that the meal set up after this period of scarcity is usually an example of caloric and nutritional imbalance - in the research, fasting usually occurred in the afternoon. “When they have access to food, the greedy individual does not make healthy choices,” explains the expert. Being deprived of energy, the body triggers a whole mechanism that favors the binge eating, the result is that the individual gets fat.

If a local population of a species goes extinct, which of the following outcomes is/are possible?a. Genetic variation may be los
insens350 [35]

Answer:

a. Genetic variation may be lost from the species as a whole

d. The overall adaptive prospects of the species may decline.

Explanation:

Genetic variations are heritable traits possess by the offspring from it progenitors. This makes the offspring to be an hybrid species because it has inherited the traits of both of his/her parents. In a local population setting goes to extinct, it might be as a result of genetic variation because these inherited variations comes in several ways, some might be adaptability to thrive in adverse weather  conditions, some production of specific hormones to combat the current state that its not suitable for them etc. so when a population shows a decline in genetic variation, such population is liable to extinction.

Also, when species can't cope with factors attached with adaptation to a particular ecosystem, (such as exhibiting camouflage in  time of danger, during dry season when food scarcity has increased etc) there will be decline in population of the species.

If there is complete linkage with genes Ss (for smooth or wrinkled seeds) and Gg (for green or yellow seeds), what phenotypes wo
KonstantinChe [14]

Answer:

Smooth and green seeds

Smooth and yellow seeds

Wrinkled and green seeds

Wrinkled and yellow seeds

Explanation:

This is a typical dihybrid cross involving two linked genes; one gene coding for seed texture and the other for seed colour. The allele for Smooth seed (S) is dominant over the allele for Wrinkled seed (s) in the first gene while the allele for green seed (G) is dominant over the allele for yellow seed (g) in the second gene.

The cross is between a heterozygous smooth, green plant and a homozygous recessive wrinkled, yellow plant

According to the law of independent assortment, each parent will undergo meiosis to produce the following gamtes with genotypes:

SsGg: SG, Sg, sG, sg

ssgg: sg, sg, sg, sg

Using a punnet square to perform a cross between these gametes ( check attached image), a total of 16 offsprings with four different phenotypes will be expected. The phenotypes are as follows:

SsGg: Smooth and green offsprings (4)

Ssgg: Smooth and yellow offsprings (4)

ssGg: Wrinkled and green offsprings (4)

ssgg: wrinkled and yellow offsprings (4)
