name the part of the blood in which most carbon dioxide is transported
Answer:
the name of part of blood in which most carbondioxide is transported are:
1) dissolved in solution
2) buffered with water as carbonic acid
3) bound to protiens, particularly haemoglobin
Look at these data. Beak depth, the distance from the top to the bottom of the beak, is controlled by the bird's
genes. The bar chart shows the variation in beak size before a drought. The survival of birds after the drought
with a particular bill depth is shown by the yellow line. Explain how these data support the idea of natural
selection among the finches.
Directional selection increased the frequency of individuals carrying the larger bill depths and decreased the frequency of individuals carring small and medium bill depths.
What is directional selection?Natural selection is an evolutive force that favors beneficial alleles and increase their frequency in the population.
Directional selection is the way in which natural selection acts on a population by increasing the proportion of individuals with an extreme phenotypic trait.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
Data on the chart Before the drought ⇒ Bar chart.The chart indicates that before the drought, the average size of the bill depth was 9.5 mm. This is an intermediate phenotype between the shortest (7.5 mm) and the largest (11 mm).
So, most individuals in the population expressed the intermediate phenotype of the bill depth.
After the drought ⇒ Line chart
The line chart indicates that, after the drought,
→ only individuals with the largest bill depth (one of the extreme phenotypes) expressed the highest survival rates.
→ Individuals with the shortest bill depth (the other extreme phenotype) expressed the lowest survival rates.
→ Individuals with the intermediate phenotype expressed an intermediate survival rate.
Directional selection favored one of the extreme phenotype -largest bill depths- over the other extreme phenotype and over the intermediate phenotype.
The frequency of individuals carrying the largest bill depths increased.

If a nerve cell stopped functioning, the cell would
F start producing oxygen.
G begin dividing into more cells.
H become a different type of cell.
J stop sending signals to the brain.
Answer:
J stop sending signals to the brain
Explanation:
If a nerve cell stopped functioning, the cell would stop sending signals to the brain. The correct option is J.
What are nerve cells?Nerve cells, also referred to as neurons, are 'excitatory' cells that can convert a variety of stimulation into electrical signals.
It usually aids in consistent sending information about the external as well as internal environment to the central nervous system in the form of action scenes of action potentials.
Neurons are the basic units of the nervous system, including the cells that receive sensory input from the outside world, send motor commands to our muscles, and transform and relay electrical signals at every phase between each one.
Thus, the correct option is J as any damage in the nerve cell can lead to impaired signaling to the brain.

If a microscope was not parfocal, how would you expect your specimen to appear when you switch from the lowest power to medium power objective?.
Answer:
Blurry
Explanation:
Parfocal lenses helps with focusing on a specimen so if the lenses are not parfocal switching to a different magnification would make it blurry and the focus needs to be adjusted.
Pancreatic fluid contains enzymes that can digest all four types of macromolecules: carbohydrates, lipids, proteins, and nucleic acids. Into which organ does the pancreas excrete those enzymes
The pancreas releases the enzymes that can digest all biomolecules located in its juice into the stomach organ of the body.
What is pancreatic juice?Pancreatic juice is a liquid substance that is produced by the pancreas organ and contains series of digestive enzymes.
According to this question, these enzymes embedded in the pancreatic juice can break down all the four biomolecules of food.
This means that the pancreas will release its enzyme-containing content into the stomach for it to act on each class of food.

PLZ help Bees need flowers that produce a lot of pollen. Which biotechnology could scientists use to make flowers full of pollen?
Answer:Pollinating insects such as honeybees play a critical role in maintaining the natural environment. The decline in honeybee populations is a global issue with significant repercussions with respect to the pollination of plants. The simultaneous expression of multifunctionality from synthesized ionic liquid gels (ILGs) for biotechnology is presented in this study. We also demonstrate that, when mixed with photochromic organic compounds, ILGs display rapid color changes, similar to light-triggered camouflage, on living Musca domestica specimens. By further exploiting the physicochemical properties of ILGs, we were able to achieve effective pollen adsorption by ILG-functionalized Formica japonica specimens from Tulipa gesneriana flowers with high biocompatibility. In addition, a radiowave-controllable bio-inspired flying robot equipped with ILG-coated vertically aligned animal hairs could be used to successfully pollinate Lilium japonicum flowers. Such materially engineered artificial plant pollinators should lead to the development of high-performance robotics that can help counter the decline in honeybee populations.

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1292 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 12^{\circ}
∘
. At some later time, the crew measures the angle of elevation from point BB to be 6^{\circ}
∘
. Find the distance from point AA to point BB
The distance from point A to point B is 1320.9 feet
What is trigonometric ratio?
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the light house, hence:
tan(12) = h/1292
h = 274.6 feet
Let d represent the distance from point B to the feet of the light house, hence:
tan(6) = 274.6/d
d = 2612.9 feet
The distance from point A to point B = 2612.9 feet - 1292 = 1320.9 feet
The distance from point A to point B is 1320.9 feet

what is the fastest land animal?
Answer:
The fastest land animal is the cheetah coming in at 80 miles per hour being the average top speed.
Explanation:
Answer:
Cheetahs are the world's fastest land animal, capable of reaching speeds of up to 70 mph.
Explanation:
At 60–90cm, the muscular tail is half the head and body length. It acts like a counterbalance, aiding high speed manoeuvring. The exceptionally long vertebral column has amazing flexibility, and as it flexes and straightens this boosts stride length.Compared with other cats, all of the leg bones are stretched. The tibia and fibula are also fused to give more stability at speed, though this interferes with climbing.

how you feel about climate change?
Tell me how you feel on one page
Answer:
I feel negative against Climate Change.
Explanation:
Climate Change is trapping Co2 into the earth's atmosphere, raising the temperature of the Earth. Because of that, it's melting the Antarctic and killing millions of animals. Not only that, but it's also causing droughts, and usually droughts are the cause(s) of famine which kill millions of not only animals, but humans too. Therefore, I feel negative emotions about Climate Change.
