A hypothetical Island lies far from any other landmasses. There are many different types of plants, but only one animal, a beetle plant and feed by chewing leaves. Given that the beetle is not exploiting all the resources on the island, which morphologic trigger an adaptive radiation of the beetles?
Answers
Answer:
a mouthpart that can pierce fruits and seeds
Explanation:
An adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms. That being said the most likely morphological change that would trigger this would be a mouthpart that can pierce fruits and seeds. This new change would allow the beetles to consume most of the different resources that the island has to offer such as the different types of plants and fruits which were previously inaccessible to the beetles.

Why is oceanic crust subducted under continental crust?
A. Oceanic crust is moving faster than continental crust.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.
Answers
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.

Answer:
All organisms are composed of cells that share a structural organization and play roles in similar biological processes.
Explanation:
All living organisms can be grouped in terms of cellular organization, functioning, and structure. These features enable us to define them as “subjects” of life. Organisms share basic biological mechanisms such as, among others, growth, homeostasis, development, energy processing, reproduction, etc. Moreover, life is also defined by the presence of essential biomolecules such as DNA, RNA, proteins and lipids. Finally, the cell is considered to be the basic unit of every life form, and organisms may be formed by one (unicellular) or more cells (multicellular). The fundamental feature of the cell is the presence of a membrane that separates it from the external environment, thereby defining its internal environment.

Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.
Answers
Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.

Identify two structural features of purines and pyrimidines. Purines contain only three ring nitrogen atoms. contain only two ring nitrogen atoms. contain four ring nitrogen atoms. contain two heterocyclic rings. contain one heterocyclic ring.
Answers
Answer:
1) Purines contain only four ring nitrogen atoms while Pyrimidines contain only two nitrogen ring atoms
2) Purines contain two heterocyclic rings while Pyrimidines contain one heterocyclic ring
Explanation:
Purines and Pyrimidines are two classes of nitrogenous bases that make up nucleic acids. They are both heterocyclic aromatic compounds which contains nitrogen atoms in their structure. Although, they are similar but have distinct features namely:
Purines are ring molecules which consists of four (4) nitrogen atoms in their aromatic structure. They are structures with two heterocyclic rings consisting of five (5) carbon and four (4) nitrogen atoms. Adenine and Guanine are the purines in nature.
On the other hand, Pyrimidines are another ring molecules consisting of two (2) nitrogen atoms in their aromatic structure. Their only ring i.e. 1, is also heterocyclic in nature and contains four (4) carbon and two (2) nitrogen atoms. Cytosine, Thymine and Uracil are the pyrimidines.

A particular cell has half as much DNA as some other cells in a mitotically active tissue. The cell in question is most likely in Group of answer choices
Answers
Answer:
This question is incomplete. Group of answer choices are:
A. G1
B. G2
C. Prophase
D. Metaphase
E. Anaphase
The correct answer is A.
Explanation:
The G1 phase (Gap 1 phase) is the period of the cell cycle from the time a cell is born until the S phase begins. When the G1 phase begins (just after the division of the stem cell) the size of the newly originated cell is half of its normal size, and the cell must grow to reach it. For this, in this period, RNA and proteins are actively synthesized. During this period, the cell has only the amount of DNA that it has received from its progenitor and each chromosome is made up of a single chromatid, since DNA replication has not yet occurred.

In the newly engineered cell created by the researchers at the JCVI, what was derived from a previous cell, partially supporting one aspect of cell theory?
Answers
Answer:
Cells can only derive from pre-existing cells.
Explanation:
The cell theory has three major postulates: 1-all organisms are composed of cells, 2-the cells are the basic unit of all living forms, and 3-the cells derive from pre-existing cells. In 2010, the J. Craig Venter Institute (JCVI) designed in the laboratory a synthetic bacterium that is able to auto replicate himself, and thereby supporting the third statement of the cell theory. This bacterium was named as Mycoplasma mycoides JCVI-syn1.0 and its creation represented a milestone in synthetic biology. M. mycoides is a bacterium that has only 473 genes coded by 531,000 bases pairs (bp), this being one of the smallest genomes of all living forms.

Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they
Answers
Answer and Explanation:
Crossing over occurs during meiosis. When homologous chromosomes are aligned and they stick together by the chiasma point. At this point, the homologous chromosomes chains break and get recombined with the broken portion of its homologous. The result is that one of the progenitor´s chromosome will have a portion of the other progenitor´s chromosome, and vice-versa.
If crossing-over does not occur, the independent assortment of the homologous chromosomes in a cell will produce two different genotypes that equals the ones of the progenitors. So, there will be two genotypes, one of them equals the female´s genotype and the other is like the male´s genotype.

a. hexokinas ::::: glucose-6-phosphatase
b. phosphofructokinase ::::: Fructose-1,6-bisphosphatase
c. pyruvate kinase :::::: pyruvate carboxylase
d. glycogen synthase ::::: glycogen phosphorylase
e. None of these
Answers
Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.

Mavis Hetherington's research, Barney would most likely be categorized as a(n)
Answers
The options are missing in this question; here are the options:
According to E. Mavis Hetherington's research, Barney would most likely be categorized as a(n)
A) defeated
B) competent loner
C) enhancer
D) good-enough
The answer to this question is A) defeated
Explanation:
E. Mavis Hetherington is an important Canadian psychologist mainly known for studying divorce and the effects of it. About this, the psychologist proposed divorce is a complex process and has a great impact on those involved. In the case of the spouses, E. Mavis Hetherington proposes four main styles spouses might acquire after divorces such as competent loner, defeated, enhancer, etc.
In the category of defeated this psychologist includes those that do not cope with life after divorce, instead, they experience depression, loneliness, regrets, and other negative feelings, which stop them from thinking positively about the future or adapting to their situation. This category describes Barney because after divorce he feels regretful and depressed; also, he has great difficulty to cope with life or adapt to the situation.
