The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.
Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.
Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.

Explanation:
The viral envelope closely resembles the ______________________. a. prokaryotic cell wall. b. capsomere c. eukaryotic cytoplasmic membrane. d. eukaryotic cell wall.
The viral envelope closely resembles the eukaryotic cell wall. That is option D.
The virus is a type of microorganism that contains DNA (Deoxyribonucleic acid) and surrounded by a protein coat.
There are different types of viruses which include:
Double stranded DNASingle stranded DNADouble stranded RNASingle stranded RNAThe parts of a virus include:
the protein coat (viral envelope)DNA (Deoxyribonucleic acid)The viral envelope is the external part of the virus, which is made up of proteins and lipids, and is capable of protecting the virus from harm.
Also the cell wall of the eukaryotic cell wall also protects these organisms from external harm.
Therefore, the viral envelope closely resembles the eukaryotic cell wall.

What must happen to a chromosome for it to become chromatin?
Answer:
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). ... However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.

Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be
Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY. This theory is not now accepted.
Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.
Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.
Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

Answer:
Monospermy and Physiological Polyspermy. In general, the entry of more than two spermatozoa into the egg cytoplasm, referred to as polyspermy, causes aberrant effects on meiosis completion or embryo development and hence embryonic death, due mainly to excess male centrosomes delivered into the egg.

What is the relationship between the light-dependent and light-independent reactions of photosynthesis
Answer:
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

what are the consequences of either an incomplete or absent ""s"" stage of the cell cycle?
Answer:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Explanation:
The consequences of an incomplete/absent "S" stage in a cell cycle are ;
A programmed cell death The cell will not move to the G2 phase of the cell cycleThe absence or incomplete "s" stage of the cell cycle occurs when the a cell does not completely copy its chromosomes or when there is a significant damage to the genetic material ( DNA ) of the cell. when any of these abnormalities occurs the "s" phase stage of the cell cycle will not be activated until the cell chromosomes are correctly copied. Therefore the cell will not move to the G2 phase of the cell cycle
Hence we can conclude that The consequences of an incomplete/absent "S" stage in a cell cycle are ; A programmed cell death and The cell will not move to the G2 phase of the cell cycle

What is photosynthesis?
Answer:
photosynthesis is the process in which plants convert light energy, carbon dioxide, and water to create glucose which it uses to feed itself and oxygen which is expelled into our atmosphere helping us breathe
Explanation:
Leaves are modified as tendrils for climbing as in
a) Cactus
b) Pea
c)Citrus
d)Bougainvillea
Answer: pea
Explanation:
In the garden pea, it is only the terminal leaflets that are modified to become tendrils. In other plants such as the yellow vetch (Lathyrus aphaca), the whole leaf is modified to become tendrils while the stipules become enlarged and carry out photosynthesis.

4. Which areas seem to be most highly and quickly affected by a continued increase in
carbon emissions?
Answer: The atmosphere will be hit hardest by the increase in carbon. As the amount of carbon increases, it leads to increased warming of the atmosphere. Rising temperatures also increase the rate of evaporation, creating a more humid atmosphere and creating a virtuous cycle of warming.
This increase is beneficial as the Earth freezes due to the absence of carbon dioxide and other greenhouse gases in the air.

Under very high pressure, the volume of a given object will decrease. What effect has the pressure inside Earth likely had on the density of materials in Earth’s core?
The effects the pressure inside Earth likely had on the density of materials in Earth’s core
What is Earth's pressure?It is made up of rock that is molten with slow-moving currents under the effect of increasing pressure and temperatures between 1,600 and 4,000 °F. Volcanic eruptions and earthquakes are caused by movement in the mantle layer.
Similar to how the temperature rises from the surface of the planet toward its center, so do the pressure. It is because of the heavy materials above, such as rocks.
The air density inside the International Space Station is kept at a level that is comparable to that of the surface of the planet. Consequently, the air pressure in the space station is equivalent to.
Therefore, the tremendous pressure inside Earth has the effect of reducing the volume of the materials, increasing their density.
