A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.
1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype? (Note, the ‘ / ‘ symbolizes the genotype of the two different homologs for a given chromosome, for example chromosome 5 homolog / chromosome 5 homolog, and ' ; ' separates different chromosomes for example 'chromosome 5 ; chromosome 8)
a. E/E ; T/T – square eyes and long tail
b. e/e ; t/t – round eyes and short tail
c. E/e ; T/t – round eyes and short tail
d. E/e ; T/t – square eyes and long tail
e. e/e ; T/T – round eyes and long tail
f. E/T ; E/T– square eyes and long tail
2. Two individuals, who are both heterozygous for eye shape and tail size, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring?
a. 9/16 will have square eyes and short tails
b. 9/16 will have round eyes and short tails
c. 3/16 will have round eyes and long tails
d. 3/16 will have round eyes and short tails
e. 1/16 will have square eyes and long tails
3. From the mating described in question ABOVE, what proportion of ALL of the offspring in will be heterozygous for both traits?
a. 1/4
b. 1/16
c. 1/8
d. 1/9
e. 3/16
f. 9/16

The reduction of hormone production during pregnancy.

Answers

Answer:

2

Explanation:

The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.

What is feedback mechanism?

The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.

The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.

Positive feedback loops and negative feedback loops are the two types of feedback loops.

Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.

Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.

Thus, the correct option is B.

The Pine Tree shown below is a common gymnosperm. Name three adaptations this tree has that allow it to live on land

Answers

A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.

Stomata (singular: stoma) are present in all land plant lineages except liverworts (similar to -but not the same as! – mosses). Stomata are pores or holes which allow for exchange of gasses (such as oxygen and carbon dioxide) between the plant cells and the environment. Stomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses.

Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).

Mutualistic association with mycorrhizal fungi, which are tightly associated with plant roots. Mychorrhizal fungi are associated with approximately 80% of all land plant species and provide additional surface area for absorption of both water and nutrients from the soil. The fungi share these resources with the plant roots, and—in exchange— the plant shares photosynthetic sugar products with the fungi.

The alternation of generations life cycle, which includes both a multicellular haploid stage and a multicellular diploid stage. Why is this an adaptation to life on land? It isn’t, in and of itself—in fact, it also occurs in *some* green algae, which are aquatic but share a common ancestor with all land plants. But specific adaptations to the alternation of generations life cycle have occurred in different lineages of plants, and those adaptations DO function as adaptations to life on land. We’ll consider these adaptations later in this reading.

These are from my text book, from last year.

Answer:

It has cuticle, a waxy, airtight seal that covers plants and allows them to retain water.

It has seeds, plant embryos without a protective cover on the scales of a cone which allows them to disperse into new locations.

It has pollen, but it is not produced in flowers, which allows it to reproduce without the need of water.

Non vascular plants are quite commin in the forests along the coast of Norther California but are relatively rare in the ecosystems around Davis in the Central Valley. What aspects of the life cycle of these plants make it difficult for them to reproduce on our area

Answers

Answer:

The Central Valley of northern California is a region where there is little water supply, while nonvascular plants cannot efficiently store water and they have primitive traits that are dependent on water for reproduction.

Explanation:

The Central Valley of northern California is characterized to have little natural precipitation/snowmelt during the dry summer months. In addition, California's climate also has extended periods of drought. On the other hand, non-vascular plants such as mosses and liverworts, are a type of plant that lacks vascular tissues (xylem and phloem), and they also lack true roots, stems, or leaves. These plants cannot efficiently absorb and store water (which fundamental for survival), and thereby the success of these plants in establishing and reproducing in the ecosystems of the Central Valley is limited to their physiological tolerance to desiccation. Moreover, non-vascular plants may also exhibit primitive traits related to their reproductive cycle (e.g., a flagellated sperm) that are dependent on water for reproduction.

A researcher is curious if Bt resistant bollworms are susceptible to an insecticide called DDT. Bollworms susceptible to Bt have genotype RR or Rr, whereas those resistant to Bt have genotype rr. Bollworms susceptible to DDT have genotype tt, whereas bollworms resistant to DDT have genotypes Tt or TT. In an effort to better understand how these two genes are inherited, the researcher crosses an RR tt bollworm with an rr TT bollworm to produce the F1 generation. Then, the researcher crosses the F1 generation to produce an F2 generation. What proportion of the F2 generation is resistant to both Bt and DDT

Answers

Answer:

The correct answer is - 3/16 or 18.75% portion will be resistant to both Bt and DDT.

Yes,there should be government regulation against known carcinogens;

Because of following reason;

food containing carcinogens cause food poison,cancer and effect our health negatively.it degrades the immunity power of us which makes us weak.if regulations is made people be awared and stop consuming those type of food.people start to consume good diet.

Answer:

Yes. I believe that there should be government regulation against known carcinogens. Take food into consideration. Before President Roosevelt passed the first Food and Drug Act, mothers would quite literally feed their children formula that could have heroin in it or any unregulated substance, because companies could do so without any repercussions. Meat factories were dangerous and its no secret that there were a significant amount of rats that fell into the meat. After this act was passed in the United States, factories cleaned up their conditions and food became somewhat safe to eat. This act protected the consumer and made them aware of what they were literally consuming. Why is this different from government regulation against carcinogens? Did you know that bug spray can contain carcinogens? Old fridges? Granite countertops? Weedkiller? Because I did not. Consumers should be aware of the contents of the things they are buying. Corporations SHOULD be held responsible for putting customers in harms way. Government legislation should be passed to protect those who do not know better. Because we should not have to know better. We should already know.
