Forensic DNA examination found the earliest known ancestors of modern
dogs occurred
Explanation:
By analyzing the DNA of two prehistoric dogs from Germany, an international research team has determined that their genomes were the probable ancestors of modern European dogs. The finding suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.

hydra aurelia sea anemone sea cucumber odd one out
Answer:
The correct answer is - sea cucumber.
Explanation:
Hydra, aurelia, and sea anemone belong to Phylum - Coelenterata or cnidaria while sea cucumber is a member of echinoderms. Cnidaria is radially symmetrical, free-swimming or fixed, aquatic and solitary or colonial animals. While sea cucumber are animals like starfish or sea urchin.
They found on the seafloor and have pentaradial symmetry however, developes bilateral symmetry later.

describe the role of prothrombin in the blood clotting process
Answer:Prothrombin is transformed into thrombin by a clotting factor known as factor X or prothrombinase; thrombin then acts to transform fibrinogen, also present in plasma, into fibrin, which, in combination with platelets from the blood, forms a clot (a process called coagulation).

In the diagram of the DNA molecule below, match the correct term with the image (ignore the blank arrow).
Answer:
hope this help
Explanation:
Nucleic acids are made up of chains of many repeating units called nucleotides (see bottom left of Figure 1 below). The DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral.) Nucleic acid molecules are incredibly complex, containing the code that guarantees the accurate ordering of the 20 amino acids in all proteins made by living cells. Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist.
This figure is a diagram of a short stretch of a DNA molecule which is unwound and flattened for clarity. The boxed area at the lower left encloses one nucleotide. Each nucleotide is itself make of three subunits:
A five carbon sugar called deoxyribose (Labeled S)
A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P)
And one of four nitrogen-containing molecules called nucleotides . (Labeled A, T, C, or G)
Alternating sugar and phosphate units form the two sides of a ladder-shaped arrangement with the rungs or steps each formed by a pair of nucleotide bases. Figure 2 below shows the structural formula of DNA in greater detail. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings. Only certain bases can pair together to form base pairs. In DNA, Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions. The side of the chain on the left begins with a free phosphate group at the top and ends with a sugar molecule at the bottom. In contrast, the complementary chain on the right begins at the top with a sugar molecule and ends at the bottom with a phosphate group.
Happily, it is not necessary to hold the details of DNA structure in your mind at all times! As the sugar and phosphate sides of the molecule are constant they are frequently represented by parallel lines. Even better, each of the nitrogen bases is conveniently represented by the first letter of its name. These conventions allow the simplified representation of the molecule shown in the figure below
Or, even easier, a section of a DNA molecule is often abbreviated to show the bases of just one strand:
A T G G C T A C
Knowing the base pairing convention of A always pairing with T and G always pairing with C makes the complementary strand of the molecule understood. It is this feature of complementary base pairing that insures an exact duplicate of each DNA molecule will be passed to its daughter cells when a cell divides.

3. (a) The binomial naming system used to identify all living things gives the Indian elephant
a scientific name of Elephas maximus.
Which part of this name refers to the genus and which part refers to the species?
genus
species
[1]
Answer:
Genus = Elephas
Species = maximus
Explanation:
Carolus Linnaeus, who is considered to be the FATHER OF TAXONOMY for his immense contribution to the classification of living organisms. Carolus Linnaeus between the year 1735 and 1758, developed a scientific system of naming organisms using two-way naming system called BINOMIAL NOMENCLATURE.
The two Latin names given to organisms were derived from their generic and specific epithet i.e. one of the names is GENUS and the other SPECIES. According to this question, the scientific name using the binomial naming system for Indian elephant is Elephas maximus. This means that Elephas is the part that refers to GENUS while maximus is the part that refers to SPECIES.

In the laboratory, scientists remove the gene for insulin from human chromosomes. They insert the gene into the DNA of bacteria. This causes the bacteria
to produce human insulin. The insulin is used to treat diabetes in humans. Which of these describe this process?
A. Recombinant DNA
B. Reproductive Cloning
C. Gene Therapy
D. DNA Fingerprinting
Answer:
A. Recombinant DNA
Recombinant DNA is created by a process called genetic recombination. In this process, we insert a exogenous gene to let another organism, a bacteria in this case, produce a protein that can not be produced otherwise

Explain why chloroplasts are found only in plant cells?
Answer:
Explanation:
Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.
Answer:
chloroplast are only found in plant cell because
it contain chlorophyll which is useful in making good for plants by trapping sunlight from
sun .
But animal don't need to make food so. they don't contain chloroplast in their cell

what is released in the light depended step of photosynthesis?
Answer: Imma say In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. ... The photosystems and electron transport chain components are embedded in the thylakoid membrane.
