The rattlesnakes are necessary to the balance of life in a forest as they eat rodents and are eaten by owls and hawks. Therefore, option (A) is correct.
What are the characteristics of rattlesnakes?Venomous rattlesnakes belong to the genera Crotalus and Sistrurus, which are members of the subfamily Crotalinae. All poisonous snakes are snakes.
Rattlers are profoundly particular, venomous reptiles with huge bodies and triangle-molded heads. Because of their distinctive "rattle" at the tip of their tails, they are one of the most well-known groups of snakes.
Rattlers are tracked down in pretty much all aspects of the mainland US, however they're particularly normal in the Southwest. Additionally, rattlesnakes can be found in South America, Central America, and Mexico.

Alaskan Wood Frogs can freeze up to 60 percent of their body. The frogs build up their glucose (sugar) concentrations in tissues and organs of the frog. This
helps prevent the cells in the tissues from shrinking or dying
Which of the following BEST explains how this adaptation increases the probability the Alaskan Wood Frog will survive in this environment?
When food sources are scarce, this allows the frog to survive until more food is readily available.
Due to the large terrain of Alaska, the frog can freeze itself to preserve energy while traveling across the state.
When harsh winter conditions develop in the area, the frog can prevent the change in the environment from affecting its homeostatic processes.
As predators seek out the frog, its senses allow it to notify the internal processes to freeze. This prevents the predator from being notified there is prey

Consider, pea plants, for which green color is dominant to yellow color, and two leaves are dominant to three. A cross between two plants that are heterozygous green and heterozygous tall is completed. What is the phenotypic ratio?
9:3:3:1
1:1:1:1
1:3:3:9
9:1:3:3
Answer:1339
Explanation:
9:3:3:1 is the phenotypic ratio, a phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
What is phenotypic ratio?The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
Researchers use the phenotypic ratio obtained from a test cross to determine gene expression for subsequent generations of an organism. A test cross is a genetics method for determining the genotypes and traits of an organism's offspring.
9/16 G-T- --> Green-colored and two-leaved plant
3/16 G-tt ----> Green-colores and three-leaved plant
3/16 ggT---> yellow color and two-leaved plant

The first phase of mitosis, in which chromosomes condense, becoming visible, the nuclear membrane dissolves, the centrosomes move to opposite ends of the nucleus, and spindle fibers form
Prophase is described as the first stage of mitosis, during which the cell begins to position itself to separate the chromatids and divide. During prophase, the nuclear envelope and nucleolus dissolve and chromosomes condense.
What is Mitosis?Mitosis is defined as the end of the cell cycle in which duplicated chromosomes separate into two new nuclei giving rise to genetically identical cells in which the total number of chromosomes remains the same. That's why mitosis is also called parity division.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase where the prophase is the first visible stage in karyokinesis. During prophase, the nuclear envelope and nucleolus dissolve and chromosomes condense.
Thus, Prophase is described as the first stage of mitosis, during which the cell begins to position itself to separate the chromatids and divide.

The law of conservation of mass states that matter can/cannot be created
or destroyed, even after a chemical change
a. Can
b. Cannot
Answer:
Cannot
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

In the Florida map shown below, use the law of superposition to determine which rocks are oldest? Map of Florida identifying four different kinds of rock strata. The top layer of quaternary rock is labeled A; the bottom layer of quaternary rock is labeled B; the top layer of tertiary rock is labeled C; the bottom layer of tertiary rock is labeled D. Public Domain A B C D
Answer:
A
Explanation:
By the law of superposition, the oldest rocks are the bottom layer of quaternary rock, labeled. The correct option is A.
What is the law of superposition?
One of the geological laws that geologists use to calculate the relative ages of strata or layers, is the law of superposition. According to this theory, rock layers are stacked or deposited one on top of the other.
The bottom will have the oldest rock strata and the top will have the youngest. Quaternary rocks are considered as oldest rocks. They can be 2.6 million years ago.
With climatic changes and the heat and pressure from the earth's crust, the rocks evolve and convert into quaternary rocks.
Thus, the correct option is A. the bottom layer of quaternary rock is labeled.

Why does dna code for proteins but not other polymers?
Answer:
The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health. The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid will be added next during protein synthesis.
In Mendel's monohybrid cross of purple-flowered and white-flowered peas, all members of the F1 generation had the __________ phenotype because their genotype was __________ at the flower-color locus.
Answer:
All members of the F1 generation had the Purple phenotype because their genotype was Pp at the flower locus.
Explanation:
Monohybrid cross is a cross involving one trait(for example Flower color).
When Mendel crossed true breeding pea plants that differed in flower color ie Purple flowered pea plant(PP) is crossed with White flowered pea plant(pp),all the seeds of F1 generation were purple.
The white flower trait did not appear in the F1 generation because the purple flower trait completely masked the white flower trait . Thus ,Purple flower trait (PP) is dominant over white flower trait(pp).
So,although the genotype of F1 seeds is Pp,the phenotype is purple flower color because the allele" P" is completely dominant over the allele "p".
