The Mesozoic era (middle life) is known as the age of dinosaurs in whcih they evolved from earlier reptiles in order to fill the niches on land, water, and in the air. This era was also where the mammals evolved but were in small size. Flowering plants also start to appear.
A niche is...A. the role an organism plays within an ecosystemB. the habitat that an organism lives inC. the areas where a species in is competition with anotherD. the food sources that one organism consumes
A niche of a species encompasses the physicial and environmental conditions that the species requires and, also, the interactions it has with other species. Therefore, the correct answer is A. the role an organism plays within an ecosystem
Congenital deafness in humans is due to the homozygous condition of either of the recessive genes d or e, or both of these genes. Both dominant D and E are necessary for normal hearing. Gene D/d affects the middle ear, while gene E/e affects the inner ear as indicated by E It does not matter how good the normal inner ear is: if there is something wrong in the middle ear, the individual is unable to hear. The same applies for the other gene. Give the phenotypic results of the following crosses: c) ddEE x DD eed) Dd EE x Dd ee
To make the punnet's square first we need to combine the allele to obtain the gametes possibilities. Then we make the cross to obtain the possible offspring
1 DdEE x 2 Ddee
Gametes:
1: DE / DE / dE / dE
2: De / De / de / de
Now we obtain the phenotypic ratios:
Given that dd/ee = deafness then:
4/16 of the offspring will have congenital deafness because of the genotype: ddEe specifically because of the dd alleles.

Which of the following is not a form of energy
Answer:
Magnetic.
Explanation:
Electric energy is the energy caused by the movement of the electric charges. The moving electric charges form the kinetic energy, thus electrical is the from of energy.
Thermal energy is the energy which usually comes from the heat.This heat is generated by the movement of tiny particles within an object. Thus, thermal energy is the form of energy.
Nuclear energy is the energy which comes from the splitting atoms in a reactor to heat water into steam and generate electricity. Thus, nuclear energy is the form of energy.
The magnets cannot be used to generate energy, as it is kind of a force which attracts a body from the another body, therefore the magnetic is not the form of energy.

Is the enzyme for lactose being made with the repressor not in place?
The lactase is an enzyme in the small intestine that breaks lactose into simpler sugar forms (galactose and glucose) that can be absorbed to generate energy. That sugar is important for gene regulation because it is linked to the Lac operon, the repressor for this structure prevents the DNA transcription, if the repressor is not in place the operon works and the enzyme is produced, being the lac repressor innately active in the absent of lactose.

4. There are several biomes that are not marked "diverse" or "non-diverse." How would you describe those biomes? (3 points)
Biomes are large areas characterized by its soil, climate, vegetacion, and wildlife. There are five major types of biomes: grassland, florest, tundra, desert, and aquatic, they still can be divided into more specific categories, such as marine (aquatic), rainflorest (florest), savanna (grassland/desert), and others. The diversity of these biomes can be based in the animails and plants of the biome, diverse biomes have a wide variety of species and are considered more livable with less environment pressure and challenges that make the area more conducive to higher diversity. The Topical florests are widely considered to have the greatest species diversity of the terrestrial biomes, with nice climate and food for the wildlife. The non-diverse biomes have extreme conditions that make them have lower diversity, for example, tundra and deserts have low diversity because of the climate and the condictions of soil and water.

Given what we now know about atmospheric and oceanic transport, are the concepts of local, regional, and global pollution still useful?
The concepts of local, regional, and global pollution are useful both in consideration of atmospheric and oceanic transport because there are pollutant substances that spread in a local way while others may encompass extended regions.
What are local, regional, and global pollution?Local pollution refers to all procedures that might contaminate a limited area such as a city or a lake, which may be avoided by recycling waste materials or avoiding the spread of residual water.
Conversely, regional pollution and global pollution affect longer-extended areas and these situations should be maintained by government policies in order to avoid harmful and or dangerous concerns (e.g. the scope of radioactive material).
Therefore, with this data, we can see that local, regional, and global pollution are useful concepts to develop measures to control different types of contaminants and pollutant substances that may affect the quality of life of people.

In a family the mother has color blindness and the father has normal vision. Their child has Klinefelter syndrome and normal vision. How is this explained and what gametes did this child give? We assume that the above parents had a child with Klinefelter syndrome and color blindness. How can this happen?
The child can have normal vision if she inherites a healthy X chromosome from the father, for this to happen, the child must be a woman.
If the child is a man, he can have normal vision as he has Klinefelter syndrome, which consist on having an extra X chromosome from his father, giving him normal vision even though the mother can only give him X chromosomes with color blindness. Moreover, this can happen as colour blindness is a recesive trait.

A barracuda stalking a school of parrot fish is an example of(A) altruistic behavior.(B) cognitive behavior.(C) competitive behavior.(D) foraging behavior. I think it’s answer (C) but I just want to make sure!
Here we have a barracuda a predator fish and parrotfish as prey, now if we analyze each available option we can see that option A is not correct as there is no benefit for the parrotfish, option B is not correct either as predation is an instinctive behavior. Now with option C, we must be careful as in the first place predation leads to competition, however, in this case, there is no mention of other predator fish be another barracuda, or other species meanwhile option D, foraging behavior implies the consumption of food, seeking, selection and manipulation of it so in this particular case, stalking a school of fish falls under this category, therefore option D is the correct answer.
how you can determine if you are looking at a Zygomycetes, Ascomycetes, or Basidiomycetes. What structures would you be looking for? Are they Sexual? Asexual?
You are looking at fungi and the structure Zygomycetes, Ascomycetes, or Basidiomycetes are used for sexual reproduction .
Zygomycota generally harvest spores inside sporangia. Ascomycota harvest spores inside asci while Basidiomycota produce spores on a platform called a basidium. The spores produced by Basidiomycota are generally made using sexual reproduction.
Zygomycota is having non-septate hyphae with numerous nuclei. Their hyphae blends during sexual reproduction to yield a zygospore in a zygosporangium. Ascomycota (sac fungi) form spores in sacs called asci during sexual reproduction. sexual reproduction is their common phenomenon of reproduction.
