Answer:

D haploid (n) with a smaller number of chromosomes than the parent cells

Explanation:

meiosis results in gametes which have half the number of chromosomes and are therefore diploid because they have one set only. that is because later, the two cells with half the chromosomes (egg and sperm) join together to make a diploid cell

The pictures show close-up views of a fir tree and a cactus.

Akimi4 [234]

The fir tree can be found in the coniferous forest biome, and the cactus can be found in the desert biome.

Option C.

<h3><u>Explanation:</u></h3>

Both the cactus and fir trees are having modified tree leaves due to the same purpose - saving water.

The fir trees are found in the coniferous forests which are mainly seen in mountains or in the temperate region. Both the regions face very cold climates and frequent snowfalls in every years. This is why there's a lack of water in the surroundings. This is why they need to save water and minimize transpiration.

Whereas the cacti are found in desert or semi arid regions where water is itself very scarce and temperature is either very high or very low. So they have their leaves converted into spines which help to reduce transpiration.

Is mixing a physical or chemical change?

Triss [41]

Sometimes you mix different substances and you don't make new substances but mostly of the time you do make new substances , so the answer is chemical change.

A cross was made between a white male dog and two different black females. the first female gave birth to eight black pups, and

Svetradugi [14.3K]

In this case, the black body colour is the dominant one. The white dog is homozygous recessive.

As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).

As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).

Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute

Type of energy from the sun that can be harmful in large amounts

BaLLatris [955]

ultra violate radition

UV is an environmental human carcinogen. It’s the most prominent and universal cancer-causing agent in our environment. There is very strong evidence that each of the three main types of skin cancer (basal cell carcinoma, squamous cell carcinoma and melanoma) is caused by sun exposure. Research shows that as many as 90% of skin cancers are due to UV radiation.
