Given the following evidence; which does not support the theory of Continental Drift? A) climate
B) fossils of plants and animals
C) magnetic strips in the ocean floor
D) land features match up (like mountains) on different continents
The theory of Continental Drift does not shows evidence about climate. Thus option A is correct.
What is continental drift?Continental drift is defined as the idea that the positions of Earth's continents have changed over geologic time, giving the impression that they have "drifted" across the ocean floor.
It can also be defined as the continents moving horizontally at a huge scale in relation to one another and the ocean basins throughout the course of one or more geologic epochs.
The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift.
Thus, the theory of Continental Drift does not shows evidence about climate. Thus option A is correct.

A population of lab rats recently escaped into the sewer system of Washington, D.C. A brave researcher sampled this population and estimated the following phenotypic frequencies, which were caused by a single gene with two alleles: E and e. 61% normal eyes (EE) 26% cross-eyed (Ee) 13% blind (ee) a) If this population were to reach a Hardy-Weinberg equilibrium (HWE) in one generation, what would the phenotypic frequencies be in that new HWE generation
Answer:
the population has a Hardy-Weinberg equilibrium
Explanation:
According to the case and the information given, the genotype frequencies are:
EE (p2) = 0.61
Ee (2pq) = 0.26
ee (q2) = 0.13
To obtain the allele frequencies we can perform the following equation
Frequency of E = p = p2 + 1/2 (2pq) = 0.61 + 1/2 (0.26) = 0.61+ 0.13 = 0.74
replacing the data we obtain:
Frequency of e = q = 1- p = 1 - 0.74 = 0.26
Regarding the expected frequencies of the genotype, taking into account that there is a Hardy-Weinberg equilibrium:
EE (p2) = (0.74) 2 = 0.547
Ee (2pq) = 2 × (0.74) (0.26) = 0.384
ee (q2) = (0.26) 2 = 0.067
We know that: (p² + 2pq + q² = 1)
replacing with the obtained data:
0.547 + 0.384 + 0.067 = 0.998 ~ 1
finally we can affirm that the population has a Hardy-Weinberg equilibrium

How do organims form carbon films
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
Explanation:
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.

As a conservationist, what are your top three concerns regarding the hydroelectric dam and the biodiversity of the region?
Answer:
I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.
Explanation:
Top three concerns regarding the hydroelectric dam and the biodiversity of the region
Hydropower can also cause environmental and social problems. Reservoirs drastically change the landscape and rivers they are built on. Dams and reservoirs can reduce river flows, raise water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.
How do hydroelectric power plants affect the environment?Hydroelectric plants alter the natural habitats of freshwater species in the areas they are located. It changes the concentration of nutrients, water temperature, and the river's flow. Downstream river flow suffers a loss of water and silt loads, reducing water quality.

Explain why coloured water moved up the stalks
Answer:
water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion
Explanation:
water moves from roots to leaves. ... Because water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion), they rise up the tubes all the way from the roots to the leaves.
Water molecules prefer to attach together and to the sidewalls of the cellulose tubes via which water travels from roots to the leaves.
Water molecules in plants:Water molecules ascend up the tubes from the roots of plants because they like to adhere together (cohesion) and attach to the walls of the cellulose tubes (adhesion).
Capillary motion is what we term when water travels into small gaps like that. Because the water particles bonded to the coloring and carried it along, the color in the water travelled up into the celery with both the water in this process. Water going into a plant in nature brings nutrients from the earth with it.

If, after adding those channels, you were to wait long enough for the system to equilibrate (i.e., reach a stable state in which the number and type of molecule in each compartment no longer changes much over time), about how many peptide molecules would you expect to find on the left side of the cell and how many on the right? How about the water molecules? Explain your reasoning.
Answer:
1 We can infer that when permeable channels are added to the peptides and a cell is incorporated in water, the concentration of peptides and water will change, generating an equilibrium causing an equivalence of equal intracellular and extracellular concentration
2. If there is no alteration and the environment is in equilibrium, we can say that there will be an equal concentration of petids and water in the intracellular and extracellular space. If we have 40 peptides on the left side, the right side will move looking for a balance and that both environments are the same, becoming 60 for each of the spaces
Although your question has some missing details a general answer is provided above
After adding the channels to a system to achieve equilibrium the number of peptide molecules on both sides of the cell have to be equal.
A difference in the peptide molecules on either side of the cell will lead to a diffusion gradient and this will lead to diffusion of peptide molecules from the side with higher concentration of peptide molecules to the side with lower concentration of peptide molecules ( this means that the system is not at a stable state ). while
A difference in the concentration of the water molecules will lead to an osmotic gradient ( this means the system is not at a stable state ).
Hence we can conclude that for the system to reach a stable state the number of peptide molecules and the water molecules on both sides of the cell should be equal.
