Flatworms, also known as Platyhelminthes, do not have a body cavity.

Flatworms are a group of invertebrate animals that have flattened, ribbon-like bodies with no internal body cavity other than a gut cavity. They lack a coelom, which is a fluid-filled cavity that is completely lined with mesoderm tissue and is present in most other animal phyla.

Earthworms, mice, clams, and nematodes all have a body cavity, either a true coelom or a pseudocoelom. The coelom or pseudocoelom serves important functions in these animals, such as providing a space for internal organs to be suspended, allowing for movement and flexibility, and acting as a hydrostatic skeleton in some species.

Answer:

1. Homeostasis the internal regulation of the body. Keeps everything at the factory setting if you will.

2. Homeostasis is all about balance which is similar to a cell membrane in that the cell membrane will only allow certain particles to pass in order to balance salt and water concentration.

3. Endotherms experience homeostasis while ectotherms do not. Ectotherms are “cold blooded” and need to use external resources to warm and cool their body.

4. Negative feedback is a key part in homeostasis in that it helps signal the body to balance something out. Example: when it’s cold you shiver and when it’s hot you sweat. Both are examples of negative feedback.

Explanation:

Soluble food molecules are absorbed into the epithelial cells of the small intestine through the process of diffusion and active transport.

The birth rate is defined as the number of births in a particular time divided by the total population. So the correct option is A.

A total number of births in a specific time (a year) divided by the total population (usually taken as 1000) is called the birth rate. The birth rate is calculated for various reasons.

Some of the things for which birth rate is needed are population count, universal registration of births etc.

Population growth is calculated using birth rate, mortality rate and migration rate from a population. The mid-year population is usually taken as the estimated population.

The birth rate is also referred to as natality. The rate of natural increase is given when the crude death rate is subtracted from the crude birth rate.

The birth rate of a population should be maintained at a moderate level by providing resources to people with children, creating awareness about methods of contraception etc.

Wheat dough is indeed derived from the grain. The process involves combining wheat flour with water and sometimes other ingredients like yeast, salt, and sugar to form a pliable, elastic dough.

This dough is then shaped and baked into a variety of baked goods like bread, pastries, and pasta.

Wheat is the most commonly used grain for making dough due to its gluten content, which gives the dough its elasticity and helps it rise during baking. Dough made from wheat flour can be used to make a wide range of dishes and is a staple in many cuisines around the world.
Wheat dough is derived from the grain by combining ground wheat flour with water and sometimes other ingredients, such as yeast and salt.

The wheat grain consists of three main parts: the bran, the germ, and the endosperm. When milled, the endosperm is primarily used to create white flour, which is then used to make dough. Wheat dough is commonly utilized for baking various types of bread, pastries, and other baked goods. The process of kneading the dough helps to develop gluten, a protein present in wheat flour, which provides structure and elasticity to the final baked product.

Answer:

I am pretty sure that the answer is (a) The way that a species creates offspring.

Explanation:

The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring.

The hormone produced in the stomach that stimulates hunger is called ghrelin.

Ghrelin is primarily synthesized and released by specialized cells in the lining of the stomach, known as the gastric oxyntic cells or X/A-like cells.

Ghrelin plays a crucial role in regulating appetite and energy balance. Its levels in the bloodstream increase before meals and decrease after eating. This hormone acts on the hypothalamus, the region of the brain responsible for regulating hunger and satiety, to stimulate appetite and promote food intake.

When the stomach is empty, ghrelin is released into the bloodstream and binds to receptors in the hypothalamus, activating orexigenic (appetite-stimulating) pathways. This stimulates the release of neuropeptides, such as neuropeptide Y (NPY) and Agouti-related peptide (AgRP), which increase appetite and food-seeking behavior. Ghrelin also affects other brain regions involved in reward and motivation, further promoting food intake.

The secretion of ghrelin is influenced by various factors, including fasting, caloric restriction, stress, and sleep deprivation. Ghrelin levels tend to be higher in individuals with conditions like anorexia nervosa or during prolonged fasting, while they decrease after consuming a meal or in individuals who are overweight or obese.

In summary, ghrelin is the hormone produced in the stomach that stimulates hunger. Its release triggers appetite and food intake by acting on the hypothalamus and activating orexigenic pathways in the brain.

Understanding the role of ghrelin helps in elucidating the complex mechanisms involved in appetite regulation and may have implications for managing conditions related to appetite and body weight.

Explanation:

Form and function are intimately related in human cells. The shape and structure of cellular components are often specifically designed to carry out their respective functions effectively. For example, red blood cells are disc-shaped with a concave center, which increases their surface area for efficient oxygen and carbon dioxide exchange. Neurons have long, branching extensions called dendrites and axons, allowing them to transmit electrical signals over long distances.

Epithelial tissues are composed of closely packed cells that form protective barriers and linings in the body. They cover external surfaces (such as the skin) and line internal organs and cavities (such as the digestive tract). In contrast, muscle tissues consist of cells that are specialized for contraction and movement. There are three types of muscle tissues: skeletal muscle, responsible for voluntary movements; cardiac muscle, found in the heart; and smooth muscle, which controls involuntary movements in organs like the intestines.

Epithelial tissues primarily function in protection, absorption, and secretion. They have tightly packed cells with minimal extracellular matrix. In contrast, muscle tissues are specialized for contraction and movement. They contain long, elongated cells (muscle fibers) that can generate force. Skeletal muscle is striated and allows for voluntary movements, while cardiac and smooth muscles have different structures and functions specific to their respective roles in the body.

In summary, the relationship between form and function is evident in human cells. Cellular structures are designed with specific shapes and arrangements to perform their functions efficiently. Epithelial tissues provide protective barriers and linings, while muscle tissues enable contraction and movement. Understanding the relationship between form and function helps us appreciate the intricate design of cells and tissues in the human body.

Answer:

Explanation:

A. having deep roots to survive grazing animals

B. having leaf shapes that do not hold water

D. having deep roots to survive fires

Plants that grow in grasslands must be able to survive in a variety of conditions, including hot temperatures, dry conditions, and frequent fires. In order to do so, they have developed a number of physical adaptations that increase their chances of survival.

One adaptation that helps plants survive grazing animals is having deep roots. These roots can allow the plant to access water and nutrients that are deeper in the soil, which can help it survive even when the surface of the soil has been damaged by grazing animals.

Another adaptation that helps plants survive in grasslands is having leaf shapes that do not hold water. This can help prevent the plant from losing water through evaporation, which is especially important in hot and dry conditions.

Having deep roots can also help plants survive fires, as these roots can allow the plant to access water and nutrients that are deeper in the soil and help it regenerate after a fire.

While having waxy leaves can help some plants retain moisture in dry conditions, it is not necessarily an adaptation that is specific to grasslands.

Answer:

Is one half the original DNA and one half new DNA with the same code as the original strand preserved

Explanation:

I am assuming the process is DNA replication.

The process of DNA replication:

step 1- the DNA double helix unwinds using an enzyme called dna helicase. Proteins hold the strands apart from each other forming a Y shape called the replication fork.

step 2- At the replication fork, enzymes called DNA polymerase move along each of the DNA strands adding complementary bases to the nitrogen bases using base pairing rules.

step 3- DNA polymerases add nucleotides to a growing double helix until all the DNA is copied

result- 2 new DNA molecules, each made of one original strand and one copied strand

An organism's fitness is determined by how well it adapts to its surroundings and reproduces.

An organism's capacity for survival and reproduction in its environment is referred to as fitness. High fitness individuals are those who have environmental adaptations that allow them to live and reproduce in their environment. Fitness, in its most basic sense, refers to an organism's capacity to persist and procreate in its environment, or, less frequently, a population or species. As a result of their ability to reproduce and survive, organisms pass on their genes to the following generation. In evolutionary biology, the ability of an organism to pass on its genetic makeup to its progeny is referred to as "fitness." Being able to live long enough to reproduce and preserve the population or species is biological fitness, also known as "Darwinian" fitness.  As a result, you could say that brown beetles had a higher fitness level if they consistently produced more offspring than green beetles due to their colour.
