Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals

Answers

Answer:

A. the wings of bees and birds

Explanation:

A homologous trait is a trait that is similar morphologically and genetically to one another due to their shared ancestry. This means that the traits are formed from the same ancestors, hence, they are homologous or similar.

According to this question, the wings of bees and birds are homologous because they share the same ancestry.

Which of the following can be inferred from the genetic code?

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answers

Answer:

A. All organisms have a common biochemical evolutionary origin.

Explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

Answers

Answer:

G phase

Explanation:

Prophase, Telophase are part of Mitosis.

Cytokinesis is the last phase of cell cycle.

Answer:

G phase

Explanation:

Which of the following is NOT a stage in the cell cycle?
A. Gap 1
B. Gap 2
C. Development
D. Mitosis

Answers

Answer:

C. Development

Explanation:

The cell cycle involves two major kinds of division; mitosis and meiosis. These divisions is each composed of stages/phases. Mitosis, for example, is divided into: interphase and mitotic (M) phase.

The interphase stage consists of Gap 1 (G1) phase, Synthesis (S) phase and Gap 2 (G2) phase while the mitotic phase consists of mitosis and cytokinesis etc. Hence, according to the question, development is not a stage of the cell cycle.

Occasionally, plates like the ones inoculated as part of this exercise are allowed to remain in the incubator for extended periods of time (two weeks or more). When the plates are examined, the agar is desiccated and Halobacterium salinarium is seen growing on plates labeled 5% NaCl and 10% NaCl, despite the fact that H. salinarium requires a minimum of 13% NaCl for growth. Explain why this happens.

Answers

Answer and Explanation:

This happened because when the agar was desiccated, all the water was released, but the solutes used in the culture medium remained in the petri dish, that is, all the nutrients remained available to H. salinarium, which survived by consuming these nutrients. Although the growth of H. salinarium requires a higher level of NaCl than the level left in the petri dish, we can consider that some colonies of H. salinarium adapted to the low level of NaCl and managed to survive, passing this characteristic to new colonies.

D. G1 phase

Explanation:

Interphase is a stage of the cell cycle that occurs between the G1, S, and G2 phases. The first gap phase is also known as the G1 phase. During this phase, the cell expands in size. It duplicates cell organelles and synthesizes molecular components necessary for mitotic division's later stages.

what is the function of red blood cells in the circulatory system​

Answers

Answer:

Red blood cells carry oxygen from our lungs to the rest of our bodies.

Explanation:

The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it's removed from the body. In invertebrates, oxygen-carrying pigment is carried free in the plasma; its concentration in red cells in vertebrates, so that oxygen and carbon dioxide are exchanged as gases, is more efficient and represents an important evolutionary development. The mammalian red cell is further adapted by lacking a nucleus—the amount of oxygen required by the cell for its own metabolism is thus very low, and most oxygen carried can be freed into the tissues.

Answers

Answer:

a)the outermost part of an animal cell that selectively allows things to pass through and come out.

b) the passing of water molecules from higher conc. to lower conc.

Answer:

(a) Semi-permeable membrane:

A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.

(b) Osmosis:

The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.

When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

how are hydrogen bond similar to iconic bonds?

Answers

Explanation:

Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. ... This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.

Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges

Answers

Answer:

How long the dog runs without stopping

Explanation:

The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.

In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.

Determine if this passage is an argument or nonargument: Evolution is central to vertebrate biology because it provides a principle that organizes the diversity we see among living vertebrates. Also it helps to fit extinct forms into the context of living species. Classification, initially a process of attaching names to organisms, has become a method of understanding evolution. --F. Harvey Pough, et al., Vertebrate Life, 7th edition Group of answer choices Nonargument Argument; conclusion: It helps to fit ... the context of living species. Argument; conclusion: Evolution is central to vertebrate biology. Argument; conclusion: Classification ... a method for understanding evolution. Argument; conclusion: It provides a principle ... among living vertebrates.

Answers

Answer:

C). Argument; conclusion: Classification,...a method of understanding evolution.

Explanation:

An argument is characterized as 'a series of propositions organized so that the final proposition is a conclusion that is intended to follow logically from the previous propositions.' The given passage exemplifies an argument as it puts forward a claim that can be argued upon if it is true or not and supported through adequate reasoning. The factual evidences are provided to support the validity of the proposition and the conclusion that 'classification initially a process...understanding evolution' is compelled. Thus, option C is the correct answer.

The "homunculus" constructed on the basis of somatosensory representations in the human primary somatosensory cortex

Answers

Answer:

The correct answer is -

a. has a grossly enlarged face and hands compared to torso and limbs

c. is distorted because of the disproportionate representation of certain body parts relative to others in the somatosensory cortex

Explanation:

" Homunculus" is a graphical representation of a small but fully grown man which the foetus is believed to develop whereas somatosensory homunculus is a neurological representation of the brain of humans that shows the motor and sensory functions of the body.

It has a large number of sensory nerves from the hand that take a large part of the brain. The face also has many nerve endings and are represented by large areas of the homunculus. A distorted look comes from this uneven representation of different body parts in the homunculus.
