Given the following phylogenetic tree, which evolutionary event occurred most recently?

A.) development of different forms of symmetry.

B.) development of tissues.

C.) each of these traits evolved at the same time.

D.) protostome and deuterostome development.

Given The Following Phylogenetic Tree, Which Evolutionary Event Occurred Most Recently? A.) Development

Answers

Answer 1

Answer:

Option-D

Explanation:

A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.

The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.

The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.

Thus, Option-D is the correct answer.

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Line t passes through (4, 5) and is perpendicular to the line shown on the coordinate grid.

a coordinate plane with a line passing through two points at 0 comma 3 and 7 comma 2

What is the equation of line t in standard form?

x − 7y = −161
7x − y = 23
−7x − y = 23
x + 7y = 161

Answers

Answer:

it is b

Explanation:

The equation of line t is [tex]7x-y=23[/tex]

Equation of line :

Given that , A line passing through two points [tex](0,3),(7,2)[/tex]

Slope of line is,

                   [tex]m=\frac{2-3}{7-0}=-\frac{1}{7}[/tex]

Since, line [tex]t[/tex] and given line are perpendicular to each other.

Slope of line [tex]t[/tex] is, [tex]=7[/tex]

Equation of line [tex]t[/tex] is, [tex]y=7x+c[/tex]

Line [tex]t[/tex] passes through [tex](4, 5)[/tex]

Substitute point in equation of line [tex]t[/tex].

             [tex]5=28+c\\\\c=-23[/tex]

Equation of line [tex]t[/tex] become, [tex]y=7x-23[/tex]

The products are stored in the form of starch because glucose is soluble

Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?

Answers

Answer:

no

Explanation:because they will find new ways to survive in the environment

Answer:

We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.

Answers

Answer:

The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.

The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.

The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.

Explanation:

The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.

In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.
