What's a node on a cladogram?
Answer:
The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node are called sister taxa.
Explanation:
Answer:
A n0de corresponds to a hypothetical ancestor. A terminal node is the hypothetical last common ancestral interbreeding population of the taxon labeled at a tip of the cladogram. ... Each internal n0de is also at the base of a clade, which includes the common ancestral population (node) plus all its
Explanation:
decendants
what determines the function of a protein
Answer:
The sequence of amino acids. - The three-dimensional shape of the folded protein. - If the coding sequence has a mutation that leads to a change in the amino acid sequence, the protein may have a different three-dimensional shape, reducing its activity.

A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
Group of answer choices
Species brought in by the storm surge will displace species native to the coastal wetlands.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Explanation:
A hurricane destroys many coastal regions of Northwest Florida which leads to the loss of habitat of many species that lives on the coastal region of Northwest Florida. This hurricane destroy the habitat that leads to decrease in population of organisms that lives in that coastal region so we can conclude that the population of organisms decreases due to this hurricane.
What is the significance of crossing over?
Answer and Explanation:
Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.
This all happens in Meiosis, which is the process of the formation of sperm and egg cells.
The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

how does water move through the water cycle
Answer:
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

a_fault is from the hanging wall drops down
Answer:
If the hanging wall moves down relative to the footwall, the fault is a normal fault. Normal faults are caused by tensional stress, or stress that pulls rocks apart

The planets, comets, and meteors of the solar system are held
(in orbit by the Sun's.
fa. Gravity
16 Spring force
I. Friction
d. Tension
Answer:
Gravity
Explanation:
Gravity keeps the planets, comets and meteors in orbit around the sun. The sun is bigger and heavier than other planets etc, this causes the planets to be pulled and kept in orbit around the sun.
Hope this helps!
The Richter scale ranges from 1 to 10 in increments of tenths and measures the amount of energy released by an earthquake, not the amount of damage or the effect on people. How many earthquakes of magnitude 4.0 does it take to release the same amount of energy released by one earthquake of magnitude 8.0? (Show your work)
What causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
How does air flow when a low-pressure center occurs in the atmosphere?
Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

what type of mutation has the least amount of impact on a protein ?
Answer: Silent Mutation
Explanation: Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.
Answer:
Point Mutations
Explanation:
It is the least harmful mutation

Which of the following best describes the genes of offspring of organisms that reproduce sexually?
Answer:
Each of the offspring is genetically unique and received some of its genetic
Explanation:
While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.
While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.
So, Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
