Answers

The two-word system that was developed by Carl Linnaeus for naming an organism is called binomial nomenclature. Carl is also known as "Father of Taxonomy". This system names species by giving them a two-part name. Both of the names of the living species are of Latin grammatical forms. Carl lived from 1707 until his death is 1778. He published a book called "Philosophia Botanica" in 1751. The book showed his way to keep up a botanical garden and his taxonomy system.

Answers

Answer:

1. b. homeostasis: The internal balance of heat within an organism is maintained by the process of homeostasis. It is the ability of the organism to maintain the internal body temperature with respect to the changes that occur in the external environment.

2.d) human: The human beings are capable for maintaining the internal temperature due to homeostasis because they exhibit fat which allows them to maintain the internal heat.

3.c) the guard cell lose pressure and the stomata open: The stomata are small pores present on the underside of the leaf surface these are important for exchange of gases and water to the external environment. The water is lost by the stomata of the leaf during transpiration. When the plant requires to remove excess of water from the plant body it is evaporated from the stomata through transpiration.

1. Homeostasis
2.Human ( a mammal)
3. B- it should be this, they swell and the stomates close, making the leaf bigger and letting it get more sunlight

Describe how the structures of the epidermis allow it to provide immediate and indirect protection to underlying tissues.

Answers

The stratum corneum is the outermost layer of the skin. It is a thick row of dead cells that contain keratin. Keratin is responsible for keeping the skin elastic and in preventing the underlying cells from drying out. The skin is called the Integumentary system of the body, it is responsible for protecting muscles, bones, and vital organs inside the body. It serves as a covering that is composed of two layers the Epidermis (outermost layer) and the Dermis (inner layer). They provide the necessary impulses for temperature control in the body through the different nerves and receptors.

A biology student is studying ways to grow crops in soils that are high in salts and other dissolved solids. To determine whether corn plants can tolerate salty soil conditions, she grows 50 corn plants in typical garden soil and the same amount of corn plants in garden soil plus varying amounts of salt: 0.01 kg, 0.1 kg, and 1 kg of salt. After 6 weeks of growth, there was an inverse relationship between amount of salt in the soil and plant height: the more salt present, the shorter the plants. The student concluded that salt had did have an effect on the growth of corn. What was the control in the experiment?

Answers
