Answer:

Kelps are characterized by three main parts: blades, stipes, and holdfasts. The blades are similar to the leaves of land plants. ... Although kelps resemble land plants, they are uniquely adapted to life in cool, clear, moving water. They depend on moving water to provide a steady supply of nutrients for photosynthesis.

Explanation:

Kelp is like a plant – it is photosynthetic and has structures that look like roots (the kelp holdfast), stems (the stipe) and leaves (blades)– but kelp and other algae belong to a separate kingdom of life from plants, called protists.

Polar bear.

Explanation:

Polar bear is the organism that has the adaptations which enable it to survive in the tundra. the polar bear has white skin and fur on all its body which helps it to camouflage in the ice and to prevent the loss of heat from its body. The polar bear catch its favourite food in the water which is the fish that provide high nutrition to the polar bear. It is a good swimmer and have large paws with small bumps that helps it to provide support while walking on the ice.

2. Direct

3. Reservoir

4. Solar cells

5. The sun heats up the atmosphere as Earth spins, creating areas of high and low temperature. This temperature difference causes wind to start moving through convection, which can then drive a wind turbine to produce electricity.

At what point in cell division is a chromosome lost so that, after fertilization with a normal gamete, the result is an embryo w
vredina [299]

Answer:

The options are missing, the options are;

I. an error in anaphase I

II. an error in anaphase II

III. an error of the first postfertilization mitosis

IV. an error in pairing

A) I or II only

B) II or IV only

C) III or IV only

D) I, II, or III only

E) I, II, III, or IV

The correct answer is A

Explanation:

Meiosis is the type of cell division undergone by reproductive cells to produce gametes that have a reduced number of chromosomes. Normally, a diploid (2n) organism like humans undergo meiosis to produce haploid gametes (n). This reduction occurs because homologous chromosomes (similar but non-identical chromosomes received from both parent) and sister chromatids are separated during the anaphase of meiosis I and II respectively. Hence each cell (gamete) at the end of meiosis now possess 23 chromosomes each as opposed to the 46 in the producing organisms.

However, an anomaly called ANEUPLOIDY can occur in which one or more chromosomes fail to separate during anaphase. This failure to separate is referred to as NON-DISJUNCTION and it results in gametes that have extra chromosomes i.e. n+1 or missing chromosomes i.e. n-1.

Note that, this error can occur in either meiosis I or II depending on whether it is homologous chromosomes or sister chromatids that fail to separate.

According to the question, a gamete with missing chromosome (n-1) is described, hence, it will undergoes fertilization to produce a zygote with 2n-1 chromosomes i.e. A diploid organism missing one chromosome (46-1) = 45 chromosomes. This particular condition is referred to as MONOSOMY.
