The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.
How to calculate genotype of a cross?According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.
If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:

9. A protein molecule which is denatured, has
a. split into smaller molecules
c. Changed its shape
b. combined with another molecule d. been diluted
Answer: B. combined with another molecule
Explanation:
i just took the test
Proteins are macromolecules composed of amino acid chains joined through peptide bonds. A denatured protein molecule has changed its shape. Thus, option c is correct.
What is protein denaturation?Protein denaturation is a process where the proteins under unfavorable conditions like temperature, chemicals, and pressure result in an alteration in their functions.
The basic structural organization of the proteins contains primary, secondary, and tertiary formation that gets altered at high temperatures resulting in the breaking of the covalent bonds and disruption of the amino acid chain.
This results in the protein breaking and forming the primary structure that leads to alteration of the shape and conformation. This change results in loss of the function and activity of the protein.
Therefore, option c. the denatured proteins result in alteration in shape.

Seeds protect the plant embryo and its food source.
Seeds provide the materials for photosynthesis.
The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction which means letter B.
What is the evolutionary importance of the seed?Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of domain for the species, competition between the newly born plant and the mother plant is also avoided.
Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.

State two arguments people might make for not preserving botana curus.
The two-argument people might make for not preserving botana curus are they take a long time to grow, so it may not be worth the effort; there are organisms that are similar, and it may be expensive.
What is botana curus?Botana curus is a precious plant because it yields Carol, a substance that can be used to treat cancer.
Curol cannot be manufactured in a lab. Botana curus grows slowly and is an endangered species, so its ability to produce large amounts of Curol is limited.
Thus, the two arguments are they take a long time to grow, so it may not be worth the effort and there are organisms that are similar, and it may be expensive.

A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product.
What is enzyme catalysed reaction?Enzyme catalysis is the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.
The model is based on the idea that the reactant passes through a transition state within the enzyme-substrate complex before the reactant is converted to the product.

Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species.
Changes to the environmental conditions can indeed result in new ecosystems and a change in the species equilibrium.
Ecosystem disruptionThe abiotic conditions of an ecosystem determine the kind of species that will inhabit the ecosystem
A change to the abiotic or environmental conditions will likely result in a new ecosystem entirely. Organisms that are able to adapt to the changes will gradually fade off the ecosystem while those that are able to withstand the changes will proliferate and dominate the populations of organisms in the ecosystem.

A. Uranium
B. Helium
C. Sulfur
Sulfur is especially important for chemotrophs living near deep volcanic thermal vents in the ocean. Therefore, option C is correct.
What are chemotrophs?An organism is said to be a chemotroph if it uses the environment's electron donors to oxidize them for energy. They might be organic or inorganic molecules. In contrast to phototrophs, which use photons, chemotrophs employ chemicals. Both autotrophic and heterotrophic chemotrophs are possible.
Prokaryotic chemotrophic organisms, which comprise both bacteria and fungi, are the most prevalent type. For all of these species to exist and procreate, carbon is necessary.

A new forensics lab will be opening soon, and the proper elements for polymerase chain reaction (PCR) analysis must be purchased. In addition to the DNA samples from the crime scenes, what other molecular items would be required
Other molecular items would be required Ions, magnesium, dNTP, primers, and buffer.
What other molecular items would be required?Polymerase chain reaction (PCR) is a technique for obtaining a large number of copies of a particular DNA fragment from a small amount of sample. It is sufficient to start from a single copy of that original fragment, or mould. This technique is based on the natural property of DNA polymerases to replicate strands of DNA, using alternating high and low-temperature cycles to separate the newly formed strands of DNA from each other after each replication phase, and then allow the strands of DNA to rejoin so that they can be duplicated again. Today, the entire PCR process is automated by means of a device called a thermal cycler, which allows the reaction tubes to be heated and cooled in order to control the temperature required for each stage of the reaction.
The common PCR is performed with cycles that have three temperature steps:
DNA denaturation double strandHybridization of the primers to the specific zone 3'of each of the strandsExtension of the primer by action of DNA polymeraseThe components necessary to carry out a PCR are:
Divalent Ions: necessary for polymerase function, magnesium ions are generally used and are in the form of magnesium chloride salt MgCl2 . The final concentration of Mg++ should be between 1.5-2.0 mM and is optimal for most PCR products.
dNTP: deoxyribonucleotides triphosphate, used by the polymerase to extend the chain.
Primers: are two short nucleotide sequences that are complementary to the DNA fragment mold. They are generally constituted between 20-40 nucleotides on average and with a GC content of 40-60%.
Buffer: Solution necessary for the reactions to take place, it is in charge of keeping the pH stable.
Taq polymerase: Enzyme in charge of DNA synthesis by adding dNTP. It supports high temperatures however has no corrective activity.
All these components are mixed in one solution.
Thus, Ions, magnesium, dNTP, primers, and buffer.
