B) Male pollen grains and female egg cells in the same reproductive organ

C) Cones containing seeds that are eaten and carried away by animals

D) Flowers designed to attract pollinators to assist in fertillization

Angiosperms have their seeds enclosed inside their fruits while gymnosperms ( non-flowering plants ) have their seeds exposed on their leave surface.The process of seeds forming after the combination of pollen and egg cells in the process of x reproduction represents a descriptive reproductive structure common in gymnosperms and angiosperms

Hence we can conclude that the reproductive structures which is common to both gymnosperms and angiosperms is seeds form after combining pollen and egg cells during x reproduction.

Scientists rely on seismic waves that travel through earth and across its surface in order to reveal the structure of the interior of the planet i.e. liquid and solid layers.

Scientists use waves to study the different layers of the earth usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test density of liquid explosions. The seismic waves are bent, sped up, slowed down, or even reflected when they pass through the earth's layers. Different types of materials density of the liquid. A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. There is evidence density of liquid that the materials within the earth form distinct layers, each with a different density of the liquid. Scientists learned that the outer core is liquid by analyzing earthquake waves. The inner core is a dense ball of solid iron crystals.

The muscular and skeletal systems work together to make the human body move as: D. They provide structure and movement to the body.

The muscular and skeletal system is also known as the musculoskeletal system. The bones of our skeletal system work on protecting the body's organs, support the weight of our body and provides shape to our body. The muscles of the muscular system which are attached to these bones, pull on them to allow the movement of the body.

The muscles in our body can pull the bones, but they can't push them back to their original position. Therefore, they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. After the movement is complete, the flexor relaxes and the extensor contracts to straighten the limb at the same joint.

According to the research, the respiratory and circulatory systems have the anatomical structures responsible for pumping and distributing blood throughout the body.

The circulatory system has the main function of transporting blood throughout the body; this blood will contain nutrients and oxygen so that they reach all the cells where the respiratory system is responsible for capturing oxygen.

In this sense, this process is carried out by means of two circuits that process blood with oxygen and deoxygenated blood:

Veins that contain oxygenated blood, such as the pulmonary veins, carry oxygenated blood from the lungs to the heart.

Therefore, we can conclude that the respiratory and circulatory systems work through two circuits to transfer oxygen and nutrients from the blood to the cells.

Energy levels in an ecosystem

To be able to calculate how much energy there is at a certain level in an ecosystem, it is necessary to understand how the energetic pyramid works: it shows the energy retained as new biomass at each trophic level.

from bottom to top:

-Solar energy

-primary producers: 100% of energy

-primary consumers: 10% of energy

-secondary consumers: 1% of energy

-tertiary consumers: 0.1% of energy

Therefore, if there is an ecosystem with 46,894 calories, to know how many calories would be at a secondary consumer level it is necessary to multiply that number by 0.01 (which corresponds to 1% of the total energy). Then:

46,894 x 0.01 = 468.94

Therefore, the correct answer to this question is option c, 468 calories.

The conclusion that Denise is most likely to write in her lab report is as follows: the data did not support the hypothesis because the amount of dissolved oxygen decreased as water temperature increased (option A).

Hypothesis in an investigation is the tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.

According to this question, Denise was performing an experiment on the effect of temperature has on the amount of dissolved oxygen that water can hold.

She then constructs an hypothesis as follows: "water temperature increases, the amount of oxygen that is dissolved in water increases"

However, the data given in the results showed that as temperature increases, the amount of dissolved oxygen decreases. Therefore, it can be said that Denise's data did not support her hypothesis.

The complete question is as follows:

Which conclusion did Denise most likely write in her lab report?

Because of this, the innermost layer is composed of nickel and iron, and the outermost layer is formed of the lightest materials, such rocks and granite.

The four layers of the earth are its inner core, outer core, mantle, and crust. The crust, mantle, and core are the three major layers of the planet.
