Which of these can be found in both gymnosperms and angiosperms?A)vascular tissue and flowers
B)vascular tissue and seeds
C)flowers and vascular tissue
D)enclosed seeds and flowers

Answers

Regarding what can be found in both gymnosperms and angiosperms, the correct choice is B)vascular tissue and seeds. Both gymnosperms and angiosperms have vascular tissue that is specialized for transport of minerals, water, and organic compounds. Also, both gymnosperms and angiosperms have seeds. The only difference is that angiosperms have seeds hidden in the ovary while gymnosperms have seed on the surface of the scales of the cones.

Answer:

"The cricket population would increase"

Explanation:

Without mice as a natural predator, there would be no regulation as to how many crickets live in an area, thus there would be an excessive amount of breeding which can lead to mutations and more sick crickets than healthy ones. The mice pick off the sick/ slower ones so the naturally stronger crickets can pass on their genes to future generations.

Answer:

The cricket population would increase.

Explanation:

If there were no more mice to eat the crickets, the crickets would have a larger population.

Which list of details describes the viviparous mode of reproduction?A. internal fertilization, development of an embryo within the female body, and the developing embryo deriving nourishment from its mother
B. external fertilization and the development of offspring outside the mother's body
C. internal fertilization and the development of an embryo within the female body without nourishment from the mother

Answers

The answer is A. internal fertilization, development of an embryo within the female body, and the developing embryo deriving nourishment from its mother

There are three different modes of reproduction:
- Ovoparity - internal fertilization, but development of offspring outside the mother's body (in eggs: ovo
- Viviparity - internal fertilization, development of an embryo within the female body, and the developing embryo deriving nourishment from its mother
- Ovoviviparity - internal fertilization, development of an egg which remains in the mother's body before the hatch and lacks nourishment from its mother.

______________ chemically alter the make-up of nutrients, changing them into a form that can be readily used by cells.A.Enzymes
B.Amino acids
C.Carbohydrates
D.Nutrients

Answers

Enzymes breaks down the food into digestibale forms. peptidases and proteases break down proteins, lipases break fats into glycerol and fatty acids, amylases break down carbohydrates into simpler utilizable sugars like glucose etc. Nucleases break down nucleic acids into nucleotides.

Enzymes chemically change the makeup of nutrient into the form that can be used by the cell.

Further Explanation:

The enzyme is the biological catalyst that participates in the chemical reaction occurring in the body of the organism. Most of them are made up of proteins.

The enzyme binds to the substrate or the reactant and then converting it into the product. They decreases the activation energy of the reaction. This allows the reactant to easily achieve the transition energy.

Enzyme acts by chemically altering the nutrient make up such that they get changed into the form which can readily be used by the cell.

Amino acids are the monomeric subunit of a polymer known as protein. These amino acids are linked to each other by the peptide linkage. The proteins are acted upon by the proteases which then converts them into the amino acids.

Carbohydrate is the biomolecule that provides energy to the body. The different types of carbohydrate are:

  • Monosaccharide
  • Disaccharide
  • Polysaccharide

Nutrients are the molecules such as carbohydrate, protein and lipids that provide energy to the body.
