birds would be least successful?
Answer:
the birds would either have two choices. they can eithe starve or they could adapt and eat the rice. they eventually would adapt if they wanted to stay alive and thrive or they would simply become extinct
Explanation:
If all of the bird types in this activity flew to an island where no birds had been before and the only food available was rice then they either starve or adapt and eat the rice.
What is adaptation?An adaptation can be defined as the heritable behavioral, morphological, or physiological trait which has evolved through the process of natural selection of a species, and maintains or increases the fitness of an organism of a species under a given set of environmental conditions and time.
In this activity, if all of the bird types flew to an island where no birds had been before and the only food available was rice then they either starve or they could adapt and eat the rice. However, they eventually would adapt if they wanted to stay alive on that island and thrive or they would simply become extinct.

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.

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?
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.

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

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
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.

for an enzyme to be able to catalyze a reaction, the active site must —
Answer:
Active site of an enzyme must be attached to a substrate
Explanation:
Active site of an enzyme must be attached to a substrate
For an enzyme to be able to catalyse a reaction, the active site must bind with the specific substrate. This is referred as 'enzyme-substrate' complex.
Why do enzymes catalyse a reaction?Enzymes have the property of catalytic activity. All the enzymes are proteinaceous in nature. Enzymes specifically bind with the substrate and thus initiates a catalytic reaction. This is referred as enzyme-substrate specificity.
Enzymes associate with the substrate at a specific site by lowering the activation energy. This forms the active site where the reaction occurs. The substrate thus transforms into the product upon the action of enzyme.
Enzymes are unique as they speed up any chemical reaction. They help in achieving the equilibrium at a faster rate. Daily thousands of enzymatic reactions are carried out in the body.
Thus, enzymes are important in the biochemistry as they persuade chemical reactions.

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