Rosa has a vegetable garden. She places earthworms, which are decomposers, in the garden soil.
What is Rosa most likely trying to do?
prevent insects from eating the plants
create usable food energy for the plants
enrich the soil with nutrients
kill the bacteria in the soil
Answer:
im pretty sure its c
Explanation:
She is trying to enrich the soil with nutrients.
Why are earthworms are important in soils?Enhanced nutritional availability: Earthworms eat on plant debris such as dead roots, leaves, grasses, manure, and dirt. Their digestive system focuses on the organic and mineral components of the food they consume. As a result, their wastes are more nutrient-dense than the soil.Drainage improvement: Earthworms loosen the soil and improve the drainage system. Earthworm-infested soils can drain water up to ten times faster than soils without earthworms. Under the effect of rain, irrigation, gravity, lime, and other materials, earthworms dig tunnels in the soil that serve as a pathway.Earthworms bind sticky soil particles together in water-stable aggregates, improving soil structure. These also aid in the storage of moisture. Increased production: Earthworms improve productivity by 70-80% after a short period of time.Thus, we can conclude that option C is correct.

The Northern Hemisphere experiences winter when Earth is farthest from the sun. True or False
Answer:
The correct answer is "False".
Explanation:
It is false to affirm that the Northern Hemisphere experiences winter when Earth is farthest from the sun. Actually, it is the opposite, the Northen Hemisphere experiences winter season when Earth is closest to the sun. Earth's distance from the sun has no major influence over the weather. The reason behind why we experience different seasons is because the Earth's axis is not straight but its is tilted. During winter season for the Northern Hemisphere, the sun shines directly on the Southern Hemisphere and indirectly on the Northern Hemisphere.
Answer:
False
Explanation:
The Earth is farthest away in its orbit when it is winter in the Northern hemisphere.

What is the primary function of a plant's root hairs?
a
Root hairs move water and minerals up.
b
Root hairs prevent excessive loss of water.
c
Root hairs move food particles up and down.
d
Root hairs provide a larger surface area for absorption.
i think it’s B if not then it’s C
Final answer:
The primary function of a plant's root hairs is to provide a larger surface area for the efficient absorption of water and minerals from the soil. Root hairs increase the root's surface area, enhancing the plant's absorption capabilities.
Explanation:
The primary function of a plant's root hairs is to provide a larger surface area for the absorption of water and minerals from the soil. Root hairs are extensions of root epidermal cells, which play a crucial role in enhancing a plant's ability to absorb these essential nutrients. The epidermis of the root provides protection and aids in absorption, while the root hairs increase the surface area available for these processes.
Negative water potential draws water into the root hairs, and the cohesion and adhesion properties of water help it to move up the plant through the vascular system, which includes the xylem and phloem. Transpiration, the process of water evaporating from leaves, also plays a part in drawing water up through the plant, from the root hairs to the leaves.
Read the following scenario: Marc's mother is remodeling the backyard. She decides to replace the grass with a concrete patio, cut down a large tree in the corner by the fence, and replace the rose garden with a rock garden fountain feature. How will this disrupt Marc's backyard biome? How with the new design change the abiotic components? What organisms will the new backyard support?
Answer:Well Its basically destroying whatever habitat had formed there. Anything living on the surface of the grace would be dead. Bees would now longer visit since there is a cut in pollen count. The only organisms the yard might support well them
Explanation:
The changes in Marc's backyard will disrupt the backyard biome by altering vegetation and abiotic components, impacting the plant and animal communities.
The replacement of grass with a concrete patio, cutting down a tree, and adding a rock garden fountain will impact the plant and animal communities.
The new design will change the abiotic components by altering sunlight exposure, soil composition, and water availability. For example, the concrete patio will reduce soil moisture and the tree removal will impact shade levels.
The new backyard may support organisms that thrive in urban environments like squirrels, birds attracted to the fountain feature, and insects that adapt to rock gardens.

A. Minor and major axes
B. Horizontal and vertical length
C. Conic and isoconic length
D. X and Y axes
Answer: Option A
Explanation:
All the planets are elliptical in shape.There are two axes found in any ellipse of all the planets. The largest diameter in the ellipse is called as the major axis of the ellipse.
The shortest diameter of the ellipse is called as the minor axis. These two lengths are found in every planets of the universe.
Answer:
Option (A)
Explanation:
Generally, an ellipse is defined as a plane curve that borders any two focal points in such a way that for all of its points lies on the curve and the sum of the two distances to their focal points must remain constant.
The shape of most of the planets usually resembles an ellipse, which is basically comprised of two axes, which represents the diameters of the ellipse. Of the two, one is the longest and the other is the smallest, that forms the major and the minor axes respectively. They are always oriented perpendicular to each other.
When both of these axes are equal in terms of length then the ellipse represents a circle.
Thus, the correct answer is option (A).

In Alaskan wolves, the allele for grey hair (G) is dominant to the allele for brown hair (g). Two grey wolves are crossed. One of the wolves is homozygous for grey hair and the other is heterozygous. What percentage of the offspring are expected to have grey hair?
a. 25%
Selected:b. 50%This answer is incorrect.
c. 75%
d. 100%
Well, if one wolf is Homozygous for the dominant G allele, then it will be GG. One is heterozygous, meaning it’s Gg. So in a punnet square you’ll end up with GG,GG,Gg,and Gg. Since heterozygous also holds that dominant trait, it works as if it were a GG. The answer is 100%
In a cross between homozygous dominant (GG) and heterozygous (Gg) grey wolves, 100% of the offspring are expected to have grey hair, thanks to the dominance of the grey hair allele.
Explanation:In this case, we are dealing with hereditary traits in Alaskan wolves specifically related to hair color. The information provided tells us that the allele for grey hair (G) is dominant to the allele for brown hair (g). When crossing two grey wolves, one of which is homozygous for grey hair (GG) and the other is heterozygous (Gg), we use a Punnett Square to determine the possible genotypes of their offspring.
The Punnett Square for these parents would look like this:
Top row: G (from GG parent), G (from GG parent) Left column: G (from Gg parent), g (from Gg parent)
The results of the cross yield: GG, Gg, GG, Gg. Therefore, because both GG and Gg wolves display the grey hair color due to the dominance of the G allele, we conclude that 100% of the offspring are predicted to have grey hair.

why dose a necturus look the way it dose
Answer:
Mudpuppies have sense organs in their skin that help them detect water movement and pressure changes. These sense organs help them avoid predators. They have small eyes that they use to see with and a good sense of smell, which they use to locate some prey.
The correct explanation for the appearance of a necturus is due to its adaptation to its environment and lifestyle.
Necturus, commonly known as the mudpuppy or waterdog, is an aquatic salamander that has a unique appearance which is a result of its evolutionary adaptations to its environment. Here are some key factors that contribute to the way a necturus looks:
1. Aquatic Lifestyle: Necturus are fully aquatic salamanders, meaning they spend their entire lives in water. Their bodies are streamlined for swimming, with broad, flat heads and tails that help them navigate their watery habitats.
2. Gills: Unlike many other salamanders that lose their gills as they mature, necturus retain their external feathery gills throughout their lives, which are visible behind their heads. These gills allow them to extract oxygen directly from the water.
3. Skin: Their skin is smooth and lacks scales, which is typical for amphibians. It is also highly vascularized, allowing for cutaneous respiration where oxygen is absorbed through the skin.
4. Coloration: Necturus typically have a gray or brownish color with dark spots or blotches, which provides camouflage against predators in the muddy or silty bottoms of the streams and lakes where they live.
5. Lungs: Although they have lungs, necturus do not rely on them as their primary means of respiration. Their lungs are simple and not as efficient as those of terrestrial salamanders, reflecting their aquatic lifestyle.
6. Limbs: They have strong limbs with webbed feet, which are adapted for walking on the substrate at the bottom of their aquatic habitats and for swimming.
7. Sensory Adaptations: Necturus have lateral line systems similar to those found in fish, which are used to detect vibrations and movement in the water, aiding in the detection of prey and predators.
8. Toxicity: Some species of necturus can secrete toxic substances from their skin as a defense mechanism against predators.
In summary, the appearance of a necturus is shaped by its need to survive and reproduce in an aquatic environment. Its physical characteristics, from its gills to its skin and limbs, are all adaptations that help it to breathe underwater, move efficiently, avoid predators, and capture prey.

Which factor affecting metamorphic process is most likely to cause foliation in a rock? A. Presence of water B. Temperature C. Pressure D. Time
Answer:
C.
Pressure is most likely to cause foliation in a rock.
Hope this helps,
One of the Virtuosos on Brainly
Answer:
Option B and C
Explanation:
The temperature and pressure causes foliation in metamorphic rock. When a rock is subject to extreme conditions, its mineral realigns itself in perpendicular direction of stress application. Foliation causes weakling of rock in a specific plane of the rock and due to this metamorphic rock break easily along the foliation planes.
As the rate of metamorphism (application of pressure and temperature) increases, the coarseness caused due to foliation also increase.
Hence, both option B and C are correct.

During prophase, the spindle fibers form. The separation of sister chromatids and the division of the cytoplasm happen in later stages of cell division.
Explanation:The event that occurs during prophase, the first phase of cell division, is the formation of spindle fibers. The microtubules that form the basis of the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. The events such as 'sister chromatids separating' or 'cytoplasm dividing' occur in later stages of cell division, not in prophase.

Moles are rodents that are very similar to mice. They live underground, spending most of their lives below the earth's surface, in the dark. Mice, on the other hand, may dig burrows to nest and sleep in, but they spend much of their time above ground. Mice also may build nests out of found materials, like cloth or grass. This difference in habitat has helped moles develop differently than mice. What adaptation would we expect to see in moles, but not in mice?
Answer:
The answer is: Moles will be less active because all they eat is mostly under ground while mice eat more things at the surface.
Explanation:
Adaptation in Moles: One key adaptation we would expect to see in moles, but not in mice, is the reduction or complete loss of eyes and visually oriented structures. This adaptation is due to the fact that moles spend their lives underground where they do not need eyes to find their way around, unlike mice that are predominantly above ground.
Vestigial Structures: The presence of vestigial structures, like covered eyes in moles, is a clear example of adaptation through evolution. These structures are body parts that no longer serve their original function due to changes in the organism's environment or behavior.
Functional Adaptations: Additionally, moles have very large front claws that are well-suited for digging and burrowing in the soil. This is another adaptation unique to moles that aids in their underground lifestyle.
