4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.​

Answers

Answer:

Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.

The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.

Explanation:

The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.

The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.

When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.

Answers

Answer:

After this, rRNA creates bonds between amino acids to make proteins.

Some important points to know:

rRNA (Ribosomal RNA) is used in the synthesis of proteins.

Amino acids are the building blocks of proteins which means that proteins are made up of amino acids.

When amino acids are joined together, they form proteins.

The bond between two or more amino acids when bonded is called "peptide bond".

Drag the inputs and outputs of cellular respiration to their correct
place.

Answers

Answer:

Inputs are: Glucose

Output are; carbon dioxide, ATP and heat

Explanation:

Cellular respiration is the metabolic process by which cells of living organisms breakdown glucose molecules to release energy (ATP). Cellular respiration, which is a must for every living organism uses oxygen (aerobic) to break down glucose (C6H12O6) into carbon dioxide (CO2) and water (H2O).

Based on the question asked, the inputs of cellular respiration are GLUCOSE AND OXYGEN while the outputs are CO2, H2O, ATP and HEAT give out. The general chemical equation is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Do environmental or genetic factors affect growth of organisms most?

Answers

Answer:

Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.

I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

d) Edited macrophage

Answers

Explanation:

Human immunodeficiency virus type 1 (HIV-1) enters target cells by first binding to the primary receptor CD4 and then to a coreceptor, generally one of the chemokine receptors CCR5 and CXCR4 (4). CD4 binding induces structural changes in the envelope (Env) glycoprotein that form and expose the coreceptor binding site. There are two main interactions between Env and coreceptor (13, 14, 25, 50, 51): the base of the third variable loop (V3) engages the N terminus of the coreceptor, while the crown of the V3 loop that includes the highly conserved GPGR/Q arch motif binds to the extracellular loops of the coreceptor, with the second extracellular loop of the coreceptor being particularly important (16, 25, 35, 48, 62). Although some HIV-1 strains are able to use a variety of different G protein-coupled receptors to gain entry into CD4+ cell lines, the great majority of these viruses use CCR5 and/or CXCR4 as coreceptors to infect primary cells (3, 4, 10, 23, 47, 66). CCR3, GPR15, APJ, and FPRL-1 are among the most frequently used alternative coreceptors when overexpressed on cell lines (11, 26, 43, 47, 57). Rare cases of HIV-1 strains that are able to use FPRL-1 and GPR1, but not CCR5 or CXCR4, have been reported (57); however, their in vivo relevance remains unknown.

To characterize the biological processes underlying HIV/simian immunodeficiency virus (SIV) transmission, we recently developed an experimental strategy that permits the identification, enumeration, and molecular cloning of transmitted/founder (T/F) viruses (28, 53). This strategy, which employs single-genome amplification (SGA) and direct amplicon sequencing of HIV/SIV RNA or DNA from the plasma or infected cells, makes it possible to infer the nucleotide sequence of the viral strain(s) that initiated productive infection weeks earlier (1, 28, 29, 37, 53, 58, 67). An important prediction of this approach has been that inferred T/F viruses are fully functional and encode all proteins necessary to establish a new infection. Indeed, this prediction has been borne out in numerous studies, which have shown that T/F viral genes as well as full-length genomes are biologically active. Sets of T/F Envs have been shown to mediate efficient virus entry in single-round infection assays, and they invariably use CCR5 as a coreceptor (28, 34). Similarly, T/F infectious molecular clones (IMCs) of HIV-1, SIVmac and SIVagm all produce replication competent virus that grow to high titers in primary CD4+ T cells (22, 38, 54).

MATERIALS AND METHODS

Amplification of the HIV-1 env gene. Serial plasma samples collected from an acutely infected plasma donor, ZP6248, were purchased from ZeptoMetrix. A total of seven plasma samples were collected between 12 February and 9 March 1997, and viral loads (VLs) were determined by the COBAS Amplicor HIV-1 monitor test.

Sequence analysis. All SGA amplicons were sequenced directly by cycle sequencing and dye terminator methods using an ABI 3730xl genetic analyzer (Applied Biosystems, Foster City, CA). Individual sequences were assembled and edited using the Sequencher program 4.7 (Gene Codes, Ann Arbor, MI). The env sequences were aligned using CLUSTAL W (60), and manual adjustment for optimal alignment was done using MASE (20).

nonsense
point
silent
frameshift

Answers

Answer:

The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in  the same amino acid to be placed next in the protein is a silent mutation.

Explanation:

Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.

An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:

                  Normal     With mutation

DNA              TTC            TTT

mRNA           AAG           AAA

Amino Acid   Lys             Lys

There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.
