A. Grasses evolved providing food to larger grazing animals, no dinosaurs which made way for mammals

Answer:

35%

Explanation:

Since we know that 35% of the bases in the section of DNA are adenine, we can conclude that 35% of the bases are thymine.

Answer:

Renewable Energy

Explanation:

The cell wall is found in plant cells but is absent in animal cells. Therefore, option C is correct.

Cell walls are a specific type of extracellular matrix that covers every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.

Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.

The pectin polysaccharide matrix, which is highly cross-linked, contains a matrix of cellulose microfibrils and cross-linking glycans that make up the cell wall. Lignin may accumulate in secondary cell walls. Therefore, option C is correct.

Answer and Explanation:

Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.

Answer:

Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.

Answer:

★ Mutated gametes (sex cells) fuse to create offspring.

Genetic mutations or germline mutations can be defined as a permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other when a mutated sperm or mutated oocyte (gametes) get fertilized with another oocyte or sperm.

A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, a single-celled zygote divides and produces all of the cells in that organism.

1. complete metamorphosis

Answer:

Complete Metamorphosis

Explanation:

This means that there are four distinct stages: an egg, larva (caterpillar), pupa (chrysalis), and adult stage. 

Answer:

See the answer below

Explanation:

Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.

Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:

Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues

Answer:

1a. To collect and remove waste materials from the body.

2c. Urinary bladder.

3d. Urea

4c. Remove urea and excess water.

Explanation:

The main function of our excretory system is to collect and remove waste materials from our body because these waste materials are toxic and cause damaged our body. Urinary bladder is the organ that stores urine. Urea is present in the urine under normal conditions of the body which is waste material produced our body. The main function of kidney is to remove urea and excess water from our body.

Answer:

B the cell will lose water

Explanation:

Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.

When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.

Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH

A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. These new, or daughter, cells are often similar in size to the old, or parent, cells.

D. Euglena and volvox contain both chloroplasts and eyespots.

Protists are single-celled microorganisms that belong to the kingdom Protista. They are unicellular organisms that are not classified as bacteria, fungi, or animals, and are the simplest of the eukaryotes (organisms with a true nucleus and other membrane-bound organelles). Protists are found in a wide variety of habitats, from freshwater to marine environments, and are important for their role in the food chain, as well as for their impact on human health.

Protists come in a wide range of shapes and sizes, from amoeba-like organisms that can change shape, to algae with chloroplasts, to parasites that can cause diseases in humans and other animals. Some protists can move on their own, while others are immobile. Some can reproduce asexually, while others reproduce sexually. Despite their diverse forms and functions, all protists are considered to be part of the same kingdom because of their shared characteristics and evolutionary relationships.
