This is true good luck on your test.
The statement "only a producer can use the sun's energy or chemical energy to make food" is true.
Who are the producers?A producer is a person who develops and offers products or services. Producers combine labor and capital, also known as factor inputs, to produce, or turn into another thing.
Business firms are the primary producers that economists typically refer to when discussing producers. The only organisms that can harvest energy from sunlight or chemicals and use it to create food are plants, some algae, and specific bacteria.
These creatures are referred to as autotrophs. In environments without sunlight, such as some marine ecosystems, this process is known as chemosynthesis.
Therefore, the statement is true.

A Hydra is an aquatic organism that lives in fresh water. During reproduction an outgrowth begins to form on the parent. The outgrowth continues to develop into the daughter organism and eventually breaks off of the parent. Which type of reproduction does this represent? A.Budding b.Regeneration c. Vegetative propagation d. Binary fission
The correct answer is: A.Budding
This is the asexual reproduction of hydra which involves production of buds in the body wall. When the buds grow enough to be miniature adults and become mature, they break away and the new organism is formed. This can happen every two days if the conditions are good for hydra (enough food). When conditions are harsh, sexual reproduction occurs.
Answer:
The answer is Budding.

How do plate tectonics explain the formation and metamorphic rocks?
Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.
When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
Plate tectonics explain the formation and metamorphic rocks as follows:
Due to the tectonic activity of the terrestrial lithosphere, igneous and sedimentary rocks formed in certain environments and under precise environmental conditions, can be subjected to new conditions (essentially pressure and temperature).
Under the new conditions, and frequently under the action of tectonic stresses (linked, for example, to the formation of mountain ranges), the pre-existing rocks are transformed, giving rise to metamorphic rocks.
Its fundamental characteristic is to present blast texture, and in the cases of having suffered deformation, anisotropic factories.
Most metamorphic rocks are the result of this phenomenon, which occurs in very large areas that are subjected to extreme temperatures, pressures, and deformations.
Along plate tectonics, mainly on the convergent plate where rocks are intensely deformed and crystallized during convergence and subduction.
Therefore, we can conclude that metamorphic rocks are the result of tectonic stresses where the rocks are intensely deformed, giving rise to metamorphic rocks.

1. In osmosis, water always moves toward the ____ solution: that is, toward the solution with the ____ solute concentration.a. Isotonic, greaterb. Hypertonic, greaterc. Hypertonic, lesserd. Hypotonic, greatere. Hypotonic, lesser
Answer:
The correct answer will be option-B (Hypertonic, greater).
Explanation:
Osmosis is the movement of water molecules via a semi-permeable membrane which depends on the solute concentration of the solution.
The water always moves from low solute concentration with high water potential to high solute concentration with low water potential.
The hypertonic solution is the solution which contains a high amount of solute due to which water potential decreases. As a result of this water molecules will move to the hypertonic solution with less amount of water.
Thus, Option-B is the correct answer.

What is the main characteristic of eusocial groups? seasonal migration periods of solitary behavior divison of labor cooperative hunting
Answer;
Division of Labor
Explanation;
Eusocial animals express complex behaviors, like group decision-making.
Eusocial animals share several characteristics which includes: adults live in groups, cooperative care of juveniles (individuals care for brood that is not their own), reproductive division of labor (not all individuals get to reproduce), and overlap of generations.
For example; Ants, termites and many species of bees and wasps form tightly integrated social groups in which permanently nonreproducing workers help rear the offspring of a few fertile individuals, the queens and males.
The main characteristic of said group is Division of Labor.

Which of these reproductive strategies are meant to ensure survival of the offspring?
A. A male sea horse carries its young in its sack
B. A peacock displays its brightly colored feathers.
C. Baby crocodiles travel on their mother’s back.
D. Bees visit the flowers of plants.
E. Birds eat fruits from trees.
The reproductive strategies meant to ensure the survival of the offspring are A, where a male seahorse carries its young in its pouch providing a protective environment, and C, where baby crocodiles travel on their mother's back for protection against predators.
Among the options provided for reproductive strategies meant to ensure the survival of the offspring, the correct choices relate to the direct care and protection of the young animals by their parents. Specifically, choices A and C involve direct protection and nurturing of offspring, which are key aspects of successful reproductive strategies in many animal species.
A. A male sea horse carries its young in its sack: This is an example of a unique reproductive strategy in seahorses, where the female lays eggs in the male's abdominal brood pouch, and the eggs are fertilized within this pouch. The male then gestates the young until birth, which provides a safe environment for the offspring during their development, greatly increasing their chances of survival.C. Baby crocodiles travel on their mother's back: This behavior provides protection to the young crocodiles from potential predators during their early life stages when they are most vulnerable.Conversely, choices B, D, and E are related to different aspects of animal behavior and do not directly contribute to the protection of offspring.

Lucas rubs a plastic ruler on his sweater. He waves the ruler above a pile of shredded paper and notices that the pieces of paper get attracted to the ruler. Which attractive force is responsible for this?
Final answer:
The attractive force observed when a charged plastic ruler attracts shredded paper is the electric force, due to the induced separation of charges within the uncharged paper.
Explanation:
The attractive force responsible for the shredded paper being attracted to the plastic ruler rubbed on a sweater is the electric force. When Lucas rubbed the ruler on his sweater, it gained an electric charge due to the transfer of electrons, a process known as triboelectric charging. The charged ruler creates an electric field around it, which induces a separation of charges within the nearby uncharged pieces of paper. The side of the paper closer to the ruler becomes oppositely charged, leading to attraction due to the electric force. This is similar to how a charged piece of tape can attract uncharged pieces of paper from a distance. The interaction observed is a fundamental expression of electrical forces between atoms, a concept that also explains why tape sticks to paper, among other human-scale forces.

The external coverings of diatoms are made up of , while slime molds have cell walls containing . Diatoms are because they make food through photosynthesis, while slime molds are because they eat decaying plant matter.
The external coverings of diatoms are made up of silica, while slime molds have cell walls containing cellulose. Diatoms are autotrophs because they make food through photosynthesis, while slime molds are heterotrophs because they eat decaying plant matter.
1. Diatoms are single-celled organisms that belong to the group of algae known as Bacillariophyta. They have a unique external covering called a frustule, which is made up of two overlapping halves that fit together like a pillbox. The frustule is composed of silica, a hard, glass-like substance. This silica shell gives diatoms their intricate and beautiful shapes, and it also provides protection for the cells.
2. Slime molds, on the other hand, are not true molds or fungi. They belong to the group of organisms known as protists. Slime molds have cell walls made of cellulose, which is a complex carbohydrate found in the cell walls of plants and some other organisms. The cellulose provides structural support and protection for the slime mold cells.
3. Diatoms are autotrophs, which means they can produce their own food through photosynthesis. They have chloroplasts, the organelles responsible for photosynthesis, which contain chlorophyll and other pigments. These pigments capture sunlight and convert it into chemical energy, allowing diatoms to synthesize organic compounds, such as glucose, from inorganic substances like carbon dioxide and water.
4. Slime molds, on the other hand, are heterotrophs, which means they cannot produce their own food. They obtain nutrients by ingesting organic matter, such as decaying plant material or bacteria. Slime molds use enzymes to break down the organic matter into simpler molecules that can be absorbed and used as a source of energy and nutrients.
In summary, diatoms have silica-based external coverings and are autotrophs that make food through photosynthesis. Slime molds have cellulose-based cell walls and are heterotrophs that obtain nutrients by consuming decaying plant matter.
Complete question :-
The external coverings of diatoms are made up of , while slime molds have cell walls containing . Diatoms are because they make food through photosynthesis, while slime molds are because they eat decaying plant matter.

You are an ecologist who discovers a new species of algae living in the fur of the brown-throated sloth. whose system of naming will you use to classify this new organism?
Answer:
You will use the Linée Classification System
Explanation:
Linée, the naturalist, physician and teacher, created a system of classification and nomenclature of living things in 1735, which is still used today with few modifications.
In Linée's system, all living things are grouped into different categories. In all there are seven taxonomic categories. The largest and most comprehensive is the kingdom. Each kingdom is divided into phyla. Each phylum is subdivided into classes. Each class is subdivided into orders. Each order is subdivided into families. Each family is subdivided into gender. Each genus is subdivided into species.
The species is the basic category. In it are individuals who are capable of reproducing among themselves and of producing fertile descendants.
Thus, the Linée Classification and Naming System is the best system for an ecologist to correctly classify and name that algae.

When scientists first started mapping human genes, they estimated that there were about 2 million genes. By the late 1990s, it was thought that there were only 100,000 genes, and then that number shrank to 19,000 in 2001. Most scientists now believe that humans have about 21,000 genes. Which statement describes these estimates?
I have the options on e2020. So first, we can definitely mark out D because no way did they stay the same over time. We can cross out B because as scientist "upgrade" over the years, their work will become MORE accurate. Not LESS accurate. So then we are left with A and C. We can cross out C because its doesn't really become accurate and less accurate over time. Then we are left with A which is our answer because scientist can only become more accurate as time goes by with all the new technology advancements they're making.

neither the experimenter nor the people in the experiment know what the experiment is about
both the experimenter and the people in the experiment know what the experiment is about
Answer:
In a double-blind experiment neither the experimenter nor the people in the experiment know what the experiment is about.
Explanation:
A double-blind experiment is when both parts lack information about the experiment, or the information that they have does not influence the results. Past experiences in the life of both experimenter and people on the experiment, can bias the results. To reduce or eliminate biases in the results, double-blind experiments are developed. Therefore, the people that designed the experiment do not administrate it.

There are 10 grams of fat 30 grams of carbohydrate and 4 grams of protein in the dessert. What percentage of calories comes from fat
Approximately 39.82% of the calories in the dessert come from fat. Therefore option 1 is correct.
To determine the percentage of calories that come from fat in the dessert, we need to calculate the energy contribution of fat and compare it to the total energy content of the dessert.
Here's an explanation of how to calculate it:
1. Determine the energy value per gram of each macronutrient:
Fat: 1 gram of fat provides 9 calories.
Carbohydrate: 1 gram of carbohydrate provides 4 calories.
Protein: 1 gram of protein provides 4 calories.
2. Calculate the energy contribution of each macronutrient in the dessert:
Fat: 10 grams of fat × 9 calories/gram = 90 calories from fat.
Carbohydrate: 30 grams of carbohydrate × 4 calories/gram = 120 calories from carbohydrate.
Protein: 4 grams of protein × 4 calories/gram = 16 calories from protein.
3. Calculate the total energy content of the dessert by summing up the energy contributions from each macronutrient:
Total calories = 90 calories from fat + 120 calories from carbohydrate + 16 calories from protein = 226 calories.
4. Calculate the percentage of calories from fat:
Percentage of calories from fat = (Calories from fat / Total calories) × 100
Percentage of calories from fat = (90 calories / 226 calories) × 100 ≈ 39.82%
Therefore, approximately 39.82% of the calories in the dessert come from fat.

Explanation:
Lipids enter the bloodstream directly after digestion. lipids enter the bloodstream directly after digestion.
a. True
b. False
Lipids, after being broken down, are absorbed by cells in the intestine, reformed into chylomicrons, and are transported through the lymphatic system before they eventually enter the bloodstream. They do not, thus, enter the bloodstream directly after digestion.
Explanation:The statement 'lipids enter the bloodstream directly after digestion' is false. Lipids are indeed broken down during digestion, but they enter the bloodstream via a slightly indirect route. During digestion, triglycerides, a type of lipid, are broken down into smaller fatty acids and monoglyceride molecules in the intestine. These smaller molecules are then absorbed by absorptive cells called enterocytes in the small intestine.
However, unlike other nutrients such as amino acids and monosaccharides, lipids don't travel directly to the bloodstream. Inside the enterocytes, the fatty acids and monoglycerides are recombined to form triglycerides again, which are then packed into vesicles called chylomicrons. These chylomicrons are released from the enterocytes and enter lacteals, which are tiny lymphatic vessels present in the intestine.
From the lacteals, chylomicrons travel through the lymphatic system and eventually reach the bloodstream. It is in this way that lipids enter the bloodstream, but not directly immediately after digestion.
