Diatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are unicellular, although they can form colonies in the shape of filaments or ribbons, fans, zigzags, or stars.

saw5 [17]

To determine the kcal of energy available from the serving of granola, multiply the number of grams of carbohydrate, fat, and protein, and fat by 4,9, and 4, respectively. Then add the results.

25 grams of carbohydrate x 4 kcal/g= 100 kcal

5 grams of fat x 9kcal/g= 45 kcal

6 grams of protein x 4 kcal/g = 24 kcal

Total= 169 kcal

stiks02 [169]

Question passage: This PASSAGE is adapted from “Rare Woodland Plant Uses‘Cryptic Coloration’ to Hide from Predators.” ©2009 byAmerican Journal of Botany, Inc.It is well known that some animal species usecamouflage to hide from predators. Individuals thatare able to blend in to their surroundings and avoidbeing eaten are able to survive longer, reproduce, andthus increase their fitness (pass along their genes tothe next generation) compared to those who standout more. This may seem like a good strategy, andfairly common in the animal kingdom, but who everheard of a plant doing the same thing?In plants, the use of coloration or pigmentation asa vital component of acquiring food (e.g.,photosynthesis) or as a means of attractingpollinators (e.g., flowers) has been well studied.However, variation in pigmentation as a means ofescaping predation has received little attention.Matthew Klooster from Harvard University andcolleagues empirically investigated whether the driedbracts (specialized leaves) on a rare woodland plant,Monotropsis odorata, might serve a similar purposeas the stripes on a tiger or the grey coloration of thewings of the peppered moth: namely, to hide.

The PASSAGE indicates that compared with other functions of coloration in plants, camouflage in plants has A) provided scientists with a deeper understanding of potential food sources. B) made use of a wider variety of distinctive shades of colors. C) proved to be a less effective defense against predators. D) been the subject of a smaller number of scientific investigations.

Answer: The correct option is C(proved to be a less effective defense against predators).

Explanation:

Adaptation is a means by which plants or animals modify their forms, structures, functions and behaviour in order to escape being harmed and survive in their environment. The special adaptations of organisms in a habitat enables them to live there successfully and reproduce. There are 3 types of adaptation which include:

--> structural adaptation,

--> adaptive coloration and

--> behavioural adaptations.

From the passage, the plant under study shows ADAPTIVE COLOURATION. Colour and colour pattern plays an important role in adaptations of plants. These occur due to the presence of pigments in cells of plants. Common pigments responsible for coloration in plants are:

--> chlorophyll: this gives green colour to plants that has chloroplasts in their cells.

--> Carotene and xanthophyll: this gives yellow to orange colour to plants that has chromoplasts in their cells.

From the passage, the use of coloration or pigmentation in the plant as a vital component of acquiring food (e.g.,photosynthesis) or as a means of attracting pollinators (e.g., flowers) has been well studied but it's use to escape from predation has received little attention. Therefore camouflage in plants has proved to be a less effective defense against predators.

Helppppppp plz thx........

Answer:

1) aa- affected

2) Aa- unaffected carrier

3) aa- affected

4) aa- affected

5) Aa - unaffected carrier

6) Aa- unaffected carrier

7) aa- affected

8) aa- affected

9) Aa- unaffected carrier

10) aa- affected

11) Aa- unaffected carrier.

This trait is recessive.

The F1 generation has a 50/50 chance of having unaffected offspring.

Explanation:

1) Given

2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier

3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)

4) They are also shaded in, so they have to have the trait

5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

6) Same reasoning as #5

7) This is shaded in, the box has to have the trait

8) Shaded in = has the trait/affected

9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

10) Shaded in = has the trait/affected

11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.

If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.
