Answer:
The products of the digestive system are actually tied directly to the circulatory system in that the organs of the digestive system are used to turn ingested food into products that can be absorbed by the blood and then carried to other organs for use as energy or other functions.
Explanation:
Answer:
b) Villi
Explanation:
The digestive and circulatory system is connected by villi.

18 The size of a mouse population in a natural
ecosystem tends to remain relatively constant due to
A. the cycling of energy.
B. the lack of natural predators.
C. the increased numbers of decomposers.
D. the carrying capacity of the environment.
Answer:
D- the carrying capacity of the environment.
Explanation:
The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant. Therefore, option (D) is correct.
What is a limiting factor in a ecosystem?Limiting factors are physical, biological, and ecological conditions that:
(1) Limit the ecosystem's ability to sustain native plant and animal populations and to accommodate natural disturbances like floods;
(2) Limit the quality or availability of habitat that supports all life stages of native species; and
(3) Limit the ecosystem's ability to sustain the local tribal culture.
The only natural factor limiting the number of mice in the home is a scarcity of resources such as food. Therefore, The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant.

The structural and functional units of the kidney are called
Answer:
The structural and functional units of the kidney are called nephron.
Fun Facts about Nephron:
Nephron is the structural and functional unit of the kidney.
Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.
The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.
The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.
What do you mean by Kidney?A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.
Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.
Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.
Therefore, the structural and functional units of the kidney are called nephrons.

how do homologous structures show common ancestry?
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
Explanation:
The correct statement is C. They demonstrate how different species differ and which creature created the structure first. Anatomical characteristics observed in several species that have a common ancestor include what are known as homologous structures.
Although these structures may have diverse purposes in many creatures, their similarities suggest that they had an ancestor.
The anatomical characteristics of several creatures may be compared to find homologous structures and deduce evolutionary links.
Because diverse kinds of creatures have homologous features, it is likely that these qualities were passed down from a common ancestor.
Similarity levels and common anatomical patterns might shed light on a species' evolutionary path.

How are the bodies of the three animals similar to one another? How are they different?
Answer:
How are animals similar? All animals are made of many cells. Most animals can move on their own. Like all living things, animals grow, change, reproduce, and respond to their environment.
Animals are made up of several cells. Most animals have independent movement. Animals develop, transform, reproduce, and react to their surroundings like all other living creatures do.
What are considered as animals?Any eukaryotic multicellular organism of the biological kingdom Animalia is referred to as an animal.
The majority of creatures in this kingdom lack a cell wall, are heterotrophic, motile, have specialised sensory organs, and originate from blastulae during embryonic development.
According to some, the fundamental distinctions between humans and other animal species are our capacity for complex reasoning, our use of complex language.
Also, the capacity for problem-solving, and the capacity for introspection (this means describing your own thoughts and feelings).
Multiple cells make up an animal. The majority of animals can move on their own. Like all other living things, animals grow, change, reproduce, and respond to their surroundings.
