Answer:

$\red{36)1m = 100cm} \\$

$\boxed{\red{right \: \: 2 \: \: places}}$

$\blue{37)1000 \: micro \: \: meter = 1mm}$

$\boxed{\blue{left \: \: 3 \: \: places}}$

$\purple{38)100000cm = 1km}$

$\boxed{\purple{left \: \: 5 \: \: places}}$

$\pink{39)1000000000000 \: micro} \\\pink{ meters = 1 \: \: megameter}$

$\boxed{\pink{left \: \: 12 \: \: places}}$

$\green{40)1km = 100000cm}$

The cheetah population was around 100,000 in 1900. Today, fewer than 12,000 cheetahs remain. What type of natural resource are c

sasho [114]

Non-renewable resource

Explanation:

The cheetahs can be considered a non-renewable resource. Non-renewable implies that a resource cannot be replenished at it current rate of depletion.

How much has the cheetah's population declined:

percentage declination = $\frac{Population in 1990}{Population today}$ x 100

Population in 1990 = 100,000

Population today = 12,000

Percentage declination = $\frac{100000}{12000}$ x 100 = 83.3%

We can see that the cheetah has suffered a whooping 83.3% decline in their population.

A renewable resource is one that can be replenished as it is being used such as water, air, e.t.c.

M protein is produced by

egoroff_w [7]

Answer:

The correct answer will be option- Streptococcus pyogenes.

Explanation:

M protein is an important virulence factor which is produced and expressed on the surface of Streptococcus pyogenes.

This protein plays important role in the bacterial infection like adherence to epidermal keratinocytes, resistance to phagocytosis, invasion of epithelial cells and microcolony formation.

The M-protein is a α-helical coiled structure protein which consists of the four distinct regions (A–D) in which A-region in the N-terminal is highly variable.

Thus, option- Streptococcus pyogenes is the correct answer.

Members of the phylum ____ are considered by many researchers to be the living plants most closely related to vascular plants, b

DIA [1.3K]

Answer: The answer is Anthocerophyta

Explanation: Anthocerophyta are widespread and occur in the temperate & tropical zones. The species of plants in this phylum have horn-shaped sporophytes which are known as "flower horn". As in other bryophytes, the sporophyte of this phylum remains attached to its parent gametophyte throughout its life, but unlike these other plants, the sporophyte continues to grow throughout its life; this happens as a group of cells at the base of the horn divide repeatedly. They also possess stomates, which exchange gases between the plant and the air.

The mitochondrial genome evolution in Anthocerophyta is closer to that of seed plants but not as dynamic.
