Homo erectus appears to have been less encephalized than Homo sapiens. Homo erectus is the older species of Homo sapiens.
Here correct answer is C
Evidence suggests that Homo erectus had a larger brain than Homo sapiens. The cranial capacity of Homo erectus ranges from 750 to 1225 cubic centimeters, depending on the region from which the skull was found, with the average being 900 ccs. In contrast, the range for Homo sapiens is between 1000–1500 ccs, with an average of 1300 ccs.
This means that Homo erectus had a slightly smaller, yet similar cranial capacity as Homo sapiens. The differences between the two species as far as cranial capacity goes is most likely attributed to natural selection.
The environment that Homo sapiens evolved in was much harsher than that which Homo erectus evolved in, and this might explain why Homo sapiens had a larger brain to help them cope with their environment.

What are the major features of ants ?Ants belongs to Formicide family which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.
The diversity of ants is every where except Antarctica.
The body has three parts such as a head, a meso-some and metasoma or gaster.
Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.
The reproduction in which young, queens fly during mating time, fertilize with male, this flight is called as nuptial flight.
Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.

why are viruses not regarded as true living cells?
Explanation:
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.
What is environment?Environment is defined as a compilation of all the factors living and nonliving and the outcomes they have on human life. Due to their ties to the forest, its plants, wildlife, water, and air. The air is filtered and hazardous gases are absorbed by the forest and trees. Plants filter water, lessen the likelihood of flooding, preserve the natural equilibrium, and do many other things.
Viruses are more like robots than actual living things, even though they do replicate and adapt to their surroundings. The viruses are thought to be dead in their natural habitat since they lack any cell-like properties. However, inside the host cell, the viruses employ the host's technological infrastructure to carry out all necessary tasks including reproduction.
Thus, viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

Students in a Biology class were formulating an argument about a cell they viewed under the microscope. Half
of the class argued it was a plant cell and the other half argued in favor of an animal cell. Below is the image the
students saw under the microscope. Which argument is supported by the image?
A. The students who said the plant cell are correct because there are chloroplasts
B. The students who said a plant cell are correct because there are mitochondria present.
C. The students who said animal cell are correct because there are chloroplasts present.
D. The students who said an animal cell are correct because there are mitochondria present.
Answer:
the answer would be A
Explanation:
Animal cells are oval and egg shaped so we can cancel out c and d
A is the correct answer because we can see green dots within the structure. Chloroplasts contain a green pigment called chlorophyll. This green pigment makes the chloroplast and the structure green (as we can see in the picture). Photosynthesis occurs in the chloroplasts, and it is where the plant gets its glucose from

Explanation:
Which types of plant cells must receive glucose from other plant cells?
Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
The type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.
Photosynthesis is a group of metabolic reactions by which plant cells generate simple carbohydrates (i.e., glucose) and oxygen by using the energy from the sun, carbon dioxide and water.In consequence, non-photosynthetic cells cannot produce glucose and thus need to receive this nutrient from photosynthetic cells.An example of non-photosynthetic cells is the root cells found underground.In conclusion, the type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.

Explain how each type of infectious agent (bacteria, virus, fungi, and parasite) affects the body.
Answer:
bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.
Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.
fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.
Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.
How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?
Answer:
See the answer below
Explanation:
The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.
The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:
Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.Why would the atomic number be better to identify an element than the atomic mass?
