Answer:

The correct answer will be option c and e.

Explanation:

Van Helmont is known for his experiment on the plants. At his time it was believed that plants take energy from the soil by eating it so he grew the willow seedlings in the pot. he measured the weight of the pot and willow seedlings and used to water it for the next five years. he measured the weight of the soil and willow seedlings after five years and found that the weight of the tree increased but the weight of the soil remained the same.

He concluded that the plant grew because of the supplied water as there was no change in the mass of the soil. His results were partly correct as he was not aware of the process photosynthesis so did not mention the carbon dioxide which increased the mass of the tree.

Thus, option c and e are the correct options.

kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc

Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
