water hyacinths still a problem till this day in the us

the answer is yes !!!!

water hyacinths also known as Pontederia crassipes considers as most  the worst aquatic weed in the world.

They are the fastest growing weed that allowed the plant to build huge populations in its ranges of introduction. They develop dense mats on the surface of the water and becoming a major weed problem.

due to their dense layering in  the surface the sun light cant travel properly in the water and the consumption of oxygen is also taken up by them hence it result the lack of oxygen in the water.

in BENGAL it is also known as the "terror of Bengal"

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.

Answers

Answer:

no it is not possible

Explanation:

bc when you do a punnett square brown hair is dominant so there is not a possible way for their child to have blonde.

yes it is, let’s say B - is for brown hair and b - is for blonde hair
to have blonde hair they would have to have a bb genotype meaning that if bob had the Bb genotype then sally and bob have a 1/4th chance of having a blonde haired child

How does a forest fire impact a population of birds that nest in the trees.

Answers

Answer:

If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.

Assuming birds escape a fire, smoke might still affect their health in ways that aren’t very well understood. Scientists have found that smoke can damage lung tissue and leave the animals susceptible to potentially lethal respiratory infections.

John and Marissa purchase their first home for $120,000. They must put 15 percent down on the purchase price as a down payment. What will the amount of the down payment be?

Answers

Answer:

Downpayment: 15% of original price

Original price: $120,000

15% of 120,000 = [tex]\frac{15}{100}[/tex] × 120,000

                          = $18,000

Thus, the downpayment is $18,000.

John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price

Original price: $120,000

15% of 120,000 =  × 12 = $18,000

Thus, the downpayment is $18,000.

What is down payment?

Part A

The down payment of $48,000 is 20% of the purchase price

Part B

A $12,000 down payment will be 5% of the purchase price

A percentage is the expression of the product of the ratio of two numbers and 100

The amount the investors buy the studio apartment = $240,000

The amount the investors have as down payment = $48,000

Part A

The ratio of the down payment the investors have and the amount the investors buy the apartment = 45,000/240,00 = 0.2

Therefore, their down payment is 0.2×100 = 20% percentage of their purchase price

Their $48,000 down payment is 20% of their purchase price

Part B

The percentage of the purchase price a $12,000 down payment would be is given as follows;

12,000/240,000 × 100 = 5%

Therefore, a $12,000 down payment will be 5% of the purchase price.

John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price

Original price: $120,000

15% of 120,000 =  × 12 = $18,000

Thus, the down payment is $18,000.

a scientist finds an organism that has a single cell without a nucleus this organism was found in pond water in which kingdom does it belong to? explain what is the answer if you find the answer i will give you 100,000 dollars

Answers

Answer:

Protista

Explanation:

In biology, there are said to be six different kingdoms that an organism can be classified under. They include Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria.

With this in mind, you say that a unicellular (single-celled) organism without a nucleus was found in pond water. This would point to the Protista kingdom, which are also known as protists. These organisms are single-celled beings with no big nucleus that are typically found in environments like ponds.

5. Drug X blocks ATP regeneration from ADP and phosphate. How will muscle cells respond to this drug?
A. by absorbing ATP from the bloodstream
B. by using ADP as an energy source
C. by using glycogen as an energy source
D. none of the above

Answers

The answer is: D - none of the above.

The muscle would contract with isotonic force. The muscle would contract isometrically. As a result of the actin-myosin cross bridges' inability to persist, the muscle would relax and lengthen. Thus, option D is correct.

What is effect of drug on ATP inhibition?

Efrapeptins and aurovertins, two types of antibiotics, prevent ATP synthase from producing or breaking down ATP.

The rotor, the core cavity of the enzyme, and the particular -subunit catalytic site are where the efrapeptins bind to ATP synthase. This is because there won't be an ATP synthase-driven proton gradient.

The inability of the inner mitochondrial membrane to remain impermeable to protons or the cessation of electron transport will prevent oxidative phosphorylation from taking place.

Therefore, muscle contract with isotonic force.

what processes in your cells produce the co2 that you exhale?

Answers

Answer:

Co2 is released from the pyruvate that is formed during glycolysis, and CO2 is also released during the citric acid cycle.

Explanation:

Cellular respiration in mitochondria produces [tex]CO_2[/tex] as a waste product, exhaled during breathing.

Cellular respiration occurs mostly in mitochondria. During cellular respiration, glucose and other nutrients are broken down to make ATP. This procedure produces [tex]CO_2[/tex]. [tex]CO_2[/tex] from mitochondria diffuses into the circulation.

Breathing exchanges [tex]CO_2[/tex] for oxygen in the lungs from the circulation. Your body releases [tex]CO_2[/tex] when you exhale. This important cycle eliminates unwanted [tex]CO_2[/tex] and supplies cells with oxygen for respiration and energy generation.

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.

Answers

Answer:

Yes, it is possible.

Explanation:

Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.

In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.
