Explain whether the female is pregnant.

Answer:

Autotrophs can make their own food.

Answer:

Bacteria are essential in cycling the nutrients back into the soil for plants to use, and cycling nitrogen back into the atmosphere. Nitrogen is found everywhere in the world, including animal waste, the atmosphere, and decaying matter.

Answer:

A primary function of water is to serve as a lubricant. For example, it is found in saliva and is a substantial component in the fluid surrounding joints. Water is also in and surrounding body structures such as the brain, spinal cord and eyes. Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand. [2] Desert sand, although plentiful, is not suitable for concrete, and 50 billion tons of beach sand and fossil sand is needed each year for construction.

Explanation:

1. What hypothesis will the experiment test?

To determine whether land or water temperatures rise quicker.

2. What are the variables?

Sand and water.

3. What purpose would the sand serve?

As a variable and to count as land. As if you were at a beach, this sand would count as the sand that the sun would be beaming on.

4. What purpose would the water serve?

As a variable and to count as the sea. As if you were at a beach, this water would count as the sea that washes on the shore.

5. What purpose would the heat lamps serve?

As what should they the same and to count as the sun. Both the water and land should have the same amount of light which would turn to thermal energy, heat.

(I'll just do the rest. I don't get paid enough for this)

6. What purpose would the thermometers use?

To track the temperature of the variables. The experiment is to find out what heats up quicker, and the thermometer is here to track that.

7. How can you use these materials to test whether land or water heats faster?

By using the sand and water as a variable to see which absorbs heat quicker, using the heat lamp to make them heat up so they don’t stay room temperature, and using the thermometer to track how hot they are in a span of time.

8. How would you compare whether land or water heats faster?

I would compare it by how hot they are using the thermometer, checking consistently for a difference.

9. Within a 24-hour period, at what three points should the temperature be taken? Why?

Within a 24-hour period only checking 3 times, they should check the temperature at the beginning (0 hours), middle (12 hours) and end (24 hours). Why? Because those are the major times. Any time before or after the middle won’t be as precise as it would’ve been, and taking the temperature at the beginning will guarantee it’s at the same starting point. At the end you’ll get the result of your experiment.

10. What would an effective conclusion need to include?

Your research results explain how your findings support or disprove your initial inference.

Answer:

Commensalism – where one species benefits while the other is unaffected.

Mutualism – both species benefit.

Parasitism – one species benefits while one is harmed.

Predation – one species benefits while the other dies.

Explanation:

Hope that helps

Answer:

Mutualism- beneficial to both organisms

parasitism- beneficial to only one organism and harms the other

commensalism- beneficial to one organism and neither harms nor benefits the other

predation- the act of killing and eating other animals

Answer: 7.69%

Explanation:

The percent error would be calculated as:

Estimated value - Actual value / Actual value × 100

300 - 325 / 325 × 100

= -25 / 325 × 100

= 25/325 × 100

= 7.69%

Hope this helps!

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Answer:

The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

Answer:

The answer is D

Explanation:

"Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. ... Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis."

Answer:

Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.

They may be unicellular or filamentous.

They reproduce by means of spores.

Fungi exhibit the phenomenon of alternation of generation.

Fungi lack chlorophyll and hence cannot perform photosynthesis

Answer:

Sound travles slower than light

Explanation:

Answer:

Interphase takes a long time because it is a preparatory stage where the cell makes proteins and organelles and doubles its chromosomes.

Interphase is when cells are dormant while they decide whether they want to replicate their chromosomes.

Interphase follows mitosis, when daughter cells double their chromosomes, which takes 23 hours.

Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is dormant while the chromosomes align

Explanation:

Gurus aided Hinduism's evolution from Brahmanism because the Upanishads, which were their ideas preserved in writings, allowed anyone to study them. Only Brahmins could study the Vedas in Brahmanism. The Upanishads are about people.

Answer:

C. A leech feeds on a host's blood.

Answer:

Porque en estas especies la fase dominante es el gametofito (haploide)

Explanation:

El ciclo de vida de las plantas superiores se caracteriza por la alternancia de generaciones, es decir por un ciclo de vida compuesto por una fase de reproducción sexual que da lugar a una generación diploide (2n), seguida por una fase de reproducción asexual que da lugar a una generación haploide (n). La fase diploide es conocida como generación esporofítica, una fase caracterizada por la formación de un cigoto diploide (2n) y producción de esporas por meiosis, mientras que la fase haploide es conocida como la generación gametofítica la cual da lugar a los gametos haploides. En plantas terrestres no vasculares (como por ej. musgos y helechos), la fase dominante es el gametofito haploide, el cual es fotosintético y autosuficiente. Por otra parte, en plantas con semillas (gimnospermas y angiospermas), la generación esporofítica es la dominante, siendo el gametofito muy reducido y dependiente del esporofito para nutrirse.

Explanation:

Answer:

c. science involves collecting and organizing data about the natural world.

Explanation:

The statement which is accurate about science is as follows:

Thus, the correct option for this question is C.

Science may be defined as a branch of scientific study that involves the application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

It can broadly be classified into three categories such as Physics, Chemistry, and biology. Each sub-classification illustrates its own field of detailed study.

Science always deals with the concept of collecting and organizing data that is significantly associated with the natural world. This branch of scientific study demonstrates valid and accurate evidence that claims facts remarkably based on the natural world and its phenomena.

Therefore, the correct option for this question is C.
