Whales accumulate carbon in their bodies during their long lifespans. When they die, they sink to the bottom of the ocean. Each large whale binds an average of 33 tons of carbon dioxide and removes this carbon from the atmosphere over centuries. Trees, on the other hand, only absorb up to 48 pounds of CO2 per year.
Rapid global warming has led to habitat loss for whales and dolphins, increasing competition for fewer and fewer prey species. It affects the timing and extent of migration, distribution and even fertility.
Scientists call large whales "ecosystem engineers." Research shows that whales cycle nutrients in the oceans, help produce the oxygen we breathe, and play an important role in mitigating greenhouse gases. Whales are not only amazing, they are breathtaking.

State a reason why the water lily lacks a waxy cuticle.
One reason why the water lily (Nymphaea spp.) lacks a waxy cuticle is because it is adapted to living in an aquatic environment. A waxy cuticle is a layer of cutin, a waterproof, protective coating found on the surface of plant leaves and stems. It helps to prevent water loss through evaporation and protect the plant from dehydration.
However, water lilies are adapted to living in an aquatic environment, where they are constantly surrounded by water. As a result, they do not need to worry about water loss through evaporation and do not have a waxy cuticle to prevent it. Instead, water lilies have evolved other mechanisms, such as thick, succulent leaves and stems, to help them absorb and store water.

The water lily lacks a waxy cuticle because it is generally present in the water, so it does not have the adaptation to save water, so it does not have the waxy cuticle, while these are the adaptations of the desert plants.
What is the significance of the water lily?The water lily is significant as it has an important role in aquatic ecosystems because it provides food for a wide variety of aquatic animals, such as insects and fish, while its roots can help stabilize shorelines, prevent erosion, and purify water by removing excess nutrients. Its seeds are of great interest to humans due to their high demands.

How does natural selection lead to increases and decreases of specific traits?
More individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits throughout the population through increases and decreases of specific traits.
Any modification to a species' structure or behavior that makes it more suited to surviving and procreating in its environment is referred to as an adaptation. Random mutations can cause the expression of particular features to become more prominent. Natural selection will result in an increase in the expression of specific features throughout the population since more people with advantageous mutations will survive than those without them.
Physical characteristics of an organism, such as the bill on a bird or the fur on a bear, are examples of structural adaptations. Behavioral adjustments make up the rest. Organisms use behavioral adaptations to help them survive. Bird migration and calls are two examples of behavioral adaptations.

Drosophila (fruit flies) usually have long wings ( ) but mutations in two different genes can result in bent wings (bt) or vestigial wings (vg). 56) If flies that are heterozygous for both the bent wing gene and the vestigial wing gene are mated, what is the probability of offspring with bent wings only
The probability of offspring with bent wings only when flies that are heterozygous for both the bent wing gene and the vestigial wing gene are mated is 25%.
This is because in genetics, the probability of offspring having a certain genotype is determined by the Punnett square, which is used to calculate the genotypic ratios of possible offspring from a genetic cross. In this case, the Punnett square would reveal a 4x4 grid in which each parent has a 50% chance of contributing either the bent wing gene (bt) or the vestigial wing gene (vg) to the offspring.
The resulting combinations would be 25% BB (both parents contributing bt), 25% btVg (one parent contributing bt and the other contributing vg), 25% Vgbt (one parent contributing vg and the other contributing bt), and 25% VgVg (both parents contributing vg). Thus, the probability of offspring with bent wings only would be 25%.

Summarize the function of water during chemiosmosis
Chemiosmosis is the passage of ions down their electrochemical gradient over a structure bound to a semipermeable membrane.
Protons, also known as hydrogen ions, will diffuse from an area with a high proton concentration to a site with a low proton concentration. Using an electrochemical gradient of protons across a membrane, ATP can be produced.
The oxidation of water, which is "divided" into protons and oxygen by the oxygen-evolving complex, replaces the electrons lost from Photosystem II (OEC, also known as WOC, or the water-oxidizing complex). Ten photons must be absorbed by Photosystems I and II, four electrons must pass through the two photosystems, and two NADPH must be produced in order to create one molecule of diatomic oxygen (later used for carbon dioxide fixation in the Calvin Cycle).

Compare the Giant's Causeway with Devils Tower. In what ways are these formations similar? In what ways are they different
The Giant’s Causeway and Devils Tower are two naturally-formed rock formations that are both located in different parts of the world and are known for their respective geological and cultural significance. Despite their vastly different locations, these two formations have many similarities.
Both the Giant’s Causeway and Devils Tower were formed by volcanic activity. The Giant’s Causeway was formed approximately 60 million years ago when a volcanic eruption caused large basalt columns to form. Devils Tower was formed even earlier, around 50 million years ago, when a volcanic intrusion solidified and created the towering formation.
Both formations have also been carved by erosion over time. The Giant’s Causeway is made up of thousands of basalt columns, which have been carved by the sea into their current shape. Devils Tower is a single, towering column of igneous rock that is estimated to have been eroded by the Belle Fourche River over millions of years.

Mendel concluded that traits can be divided into overt and latent traits. He named these dominant and recessive traits respectively. Dominant traits are traits that are inherited unchanged by hybridization.
Mendel developed his three principles of heredity to explain the transmission of hereditary traits before anyone knew that genes existed. Mendel's laws of inheritance greatly expanded our understanding of heredity and led to the development of new experimental methods.
Mendel's conclusion:
Genetic determinants are unique in nature. These determinants are called genes. Each parent has a pair of genes in each cell for each trait tested. F1 from a cross between two pure strains contains one allele with a dominant phenotype and one allele with a recessive phenotype.

Compare and contrast the properties of oceanic crust and continental crust
Oceanic crust is generally younger than continental crust, being less than 200 million years old. It is made of basaltic rock, which is denser and more mafic than the granitic rock found in continental crust. Oceanic crust is thinner and more dense than continental crust, with average thickness of about 6 kilometers compared to about 35 kilometers for continental crust. Oceanic crust is also less buoyant and more prone to subduction.
Continental crust is generally thicker and less dense than oceanic crust, and is composed mainly of granitic rock. It is much older than oceanic crust, having formed over billions of years, and is also more buoyant due to its lower density. Continental crust is less prone to subduction and therefore is more likely to form mountains and landforms. It is also much thicker, with an average thickness of about 35 kilometers.

Answer:
Explanation:
Both ferns and cedar trees rely on wind-dispersed pollen to successfully fertilize themselves.
Ferns are a group of vascular plants that reproduce via spores. These spores are produced in clusters called sori, which are found on the underside of fern fronds. The spores are released from the sori, and are carried away by the wind to fertilize other ferns.
Cedar trees, which are coniferous trees, also rely on wind to disperse their pollen. The male and female cones of the tree are separate, with the male cones releasing pollen into the air which is carried by the wind to fertilize the female cones on the same or nearby trees.
Both ferns and cedar tree do not produce flowers or rely on animal vectors (like bees or butterflies) for pollen transport, they use the wind to move their reproductive cells and complete the fertilization process.
