The function of enzymes in plants is:

Cacti grow slowly due to the fact that they keep their stomata closed for much of the day. why would closing their stomata durin

gogolik [260]

Cacti grow in the desert, which is a very hot climate. Not the best for both gaining and maintaining water supplies, due to the fact that water becomes vapour very quickly in conditions such as a desert (unless we're talking about polar deserts).

Keeping their stomata closed during the day stops water vapour from escaping their cells. While this does inhibit growth and stop new water molecules from entering, it allows the cactus to maintain a healthy amount of water within itself.

Geosphere is the sphere containing sediments as well as rocks

hydrosphere can be regarded as the sphere which contains total amount of water that exist on a planet.

The geosphere can be regarded as the collective name that is used to call the atmosphere of the earth lithosphere as well as hydrosphere, and cryosphere.

The geosphere can be regarded as sphere which contains the rocks as well as minerals on Earth

The geosphere is also the sphere with abiotic/non-living parts of soils as well as the skeletons of animals, it also contains sediment as well as rocks.

An atmosphere can be regarded as the layers which consists of gases which envelope a planet.

Therefore, geosphere is collection of spheres containing sediments as well rocks.

In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrin

meriva

Assuming the genes are not linked nor interacting with each other, the expected number of long stemmed plants with purple flowers, producing wrinkled peas, L-P-rr, is 288.

<h3>Available data</h3>

long stems are dominant to short stems
purple flowers are dominant to white,
round peas are dominant to wrinkled

Each trait is determined by a single, different gene.

A heter0zyg0us plant is self-crossed
F1) 2,048 descendants

Let us name te alleles as follows

L ⇒ Long stem
l ⇒ Short stem
P ⇒ Purple flowers
p ⇒ white flowers
R ⇒ Round peas
r ⇒ wrinkled peas

Cross) heter0zyg0us plant is self-crossed

Parental) LlPpRr

Gametes) LPR, LPr, LpR, Lpr, lPR, lPr, lpR, lpr

Assuming that these genes are not linked nor interacting with each other, to make the calcs easier we will make crosses considering each gene separately.

Stems

Parental) Ll x Ll

F1) 1/4 LL, 2/4 Ll, 1/4 ll

3/4 long stem, 1/4 short stem

Flower color

Parental) Pp x Pp

F1) 1/4 PP, 2/4 Pp, 1/4 pp

3/4 purple flowers, 1/4 white flowers

Peas

Parental) Rr x Rr

F1) 1/4 RR, 2/4 Rr, 1/4 rr

3/4 round peas, 1/4 wrinkled peas

Now, we will get the proportion of individuals with long stems, purple flowers, producing wrinkled peas, L-P-rr

Note: The symbol - is representing either a dominant or a recessive allele.

From the crosses, we know that

3/4 are long stemmed,
3/4 have purple flowers, and
1/4 have wrinkled peas.

To get the proportion of individuals expressing all these traits together, we just need to multiply these values.

3/4 L- x 3/4 P- x 1/4 rr = 9/64 L-P-rr

Knowing that the total number of plants is 2,048 and that there are 64 possible gametes combinations from this cross, we will use the proportion 9/64 to get the number of plants with these traits.

64 ------------- 2,048 plants

9 -------------- X = (9 x 2048) / 64 = 288 plants.

We expect to find 288 long stemmed plants with purple flowers, producing wrinkled peas.

Explain how animal like plant like are similar and different

Delvig [45]

Answer: The main way animal-like protists differ from plant-like protists is in the way they get energy. Animal-like protists are heterotrophs. ... Plant-like protists, on the other hand, are autotrophs. They can make their own energy from the sun or other sources just as plants can.
