A learner was walking along a road when she saw an object under a tree. When the learner touched the object, it rolled over and divided into two . Which characteristics of living organisms did the object show?

Answers

Answer:

growth, reproduction, and sensitivity

Explanation:

The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.

When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.

When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.

By dividing into 2, the object has increased its number of cells and has also produced a new individual.

Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity

a) Antonie Van Leeuwenhoek is considered to be the first microbiologist. His work was completed before Pasteur's. He was the first to use microcscopes to observe and describe single-celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. How did Van Leeuwenhoek's work provide the basis for Pasteur’s work on disproving the theory of spontaneous generation? (4 points)

Answers

Answer:

Explanation:

The spontenous genrration theory states that living organisms can be spwan without descent of similar organisms; so in other words, it is possible for living creatures could arise from nonliving matter such as water. Similarily in 1676 Van Leeuwenhoek discovered tiny organisms living in his cup of water- the first bacteria observed by man. Pasteur's spontenous generation theory came into the limelight after his most noteable experiment in 1859; in which he boiled meat broth in down ward tipped flasks. It is importnat to note that the tip of the flask (the neck) is what prevented particles to fall freely and instead the bent neck allowed air to travel through the flask- if the flask were to be tilted on its side the particles would seep into the broth and create a cloud within the flask. Pastuer further decided to boil the broth to possible create bacietia. Boiling the broth exposed the contents to air vessels which contained a filter to stop the particles from seeping thorugh into the broth.  What Pastueru concurred from his experminet was that flasks with filters and no filters that did not allow the particles to pass into the medium of the flask, were unsucessful with createing bacteria life. Thus, Pasteur found that noithing  grew in the flasks unless they were broke open, disapproving that living organisms could be spotenously generated within the broth, was instead created from outside the inards of the flask- and were created as spores or dust.

List the energy transformations from the sun until energy is lost​

Answers

Answer:

Chemical Energy - Mechanical Energy and Heat

Explanation:

The energy that is in the sunlight gets absorbed by plants and gets turned into chemical energy by photosynthesis.

Than this energy is transferred to animals who eat the plants as chemical energy.

Lastly the ATP that contain the chemical energy gets burned in the cells and gets turned into mechanical energy and heat-loss to the environment.

Water molecules are polar. Explain the distribution of charge in a molecule of water.

Answers

Answer:

Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atom.

Water molecules are polar because it determines the bent shape of the molecule in which the partial negatively charged atoms are covalently bounded to the partial positively charged hydrogen atoms.

What are the other characteristics of water molecules?

The other characteristics of water molecules are as follows:

It acts as a universal solvent.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.

The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.

This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.

Therefore, it is well described above.

Provide a food web for Grassland starting with the Earth's primary source of energy.​

Answers

Answer:

Sun energy >>> Grass >>> Mouse >>> Fox >>> Puma/Mountain Lion>>>Microorganisms.

Explanation:

Organisms that can synthesize inorganic substances, such as light, and turn it into food according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, that photosynthesize.  Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy.  In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers.  

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

In the exposed example of a food web for Grassland, we can differentiate:

Producer: Grass. An autotrophic organism that synthesizes organic matter from the sun energy. These species reproduce sexually and produce seeds for dispersion. These seeds are also an important source of food for many animals.Herbivores (Primary consumer): Mouse. A heterotrophic animal that feeds on the seeds of the grasses. Carnivore (Secondary consumer): Fox. A carnivore heterotrophic animal that hunts mouses and feeds on them.Carnivore (Tertiary or superior consumer): Puma/Mountain lion. A superior consumer, carnivore heterotrophic animal that hunts foxes and feeds on them.Decomposers: Microorganisms. When the puma dies, these organisms degrade the animal´s organic matter

Explanation:

Germ cells are the cells that have ability to divides in to gametes that will fused with the gametes of opposite sex to reproduce sexually and produce offspring.

Meiosis is one of the cell division process where one cell goes under the division twice to make four cells with the half of the genetic content than the parent cells. These cells are gametes or sex cells known as sperm in males, eggs in females.

In this process germ cells go under division twice to produce four daughter cells that are haploid, in males these cells are called as sperms, whereas in females the three cells become polar bodies and the fourth cell termed as egg.

Thus, the correct answer is : 4, and 1.

A blow to the cheek is most likely to break which superficial bone or bone part? (a) superciliary arches, (b) mastoid process, (c) zygomatic arch, (d) ramus of the mandible

Answers

Answer:

The correct answer is option c, that is, zygomatic arch.

Explanation:

In anatomy, a section of the skull produced by the temporal bone’s zygomatic process and the zygomatic bone’s temporal process is known as the cheekbone or the zygomatic arch. Temporal bone refers to a bone, which protrudes frontward from the skull side, that is, over the opening of the ear, while the zygomatic bone is the lateral to the cheekbone.  

When a blow takes place to the cheek then the superficial bone or the part of the bone that breaks most likely is the zygomatic arch.

What are atoms?

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.

Moreover, at the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.

Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive.
