Bacteria are organisms, although they are unicellular and do not have organelles like multicellular organisms. So, the given statement is False.
What is Bacteria?Microorganisms which are unicellular, prokaryotic, and have a straight cell structure are known as bacteria. They are present in almost every part of the planet, including soil, water and the human body. Many ecological and biological processes, such as nutrient cycling, decomposition, and symbiosis, depend heavily on bacteria.
While some bacteria can cause disease, many others, such as those that live in the gut and support digestion, are helpful and important for maintaining human health. Bacteria can vary in shape, size, and structure, and they can be divided into several categories according to these characteristics.
Therefore, the given statement is False.

Describe how the regeneration of the anole's tail showed both cell division and cell differentiation.
Please help need answers quick!!!
Answer:
In adult organisms the regenerative capacity of certain organs or tissues can be limited, resulting in an important clinical challenge for physicians and scientists [1-3].
Regeneration involves the capacity for renewal or recomposition of tissues, organs or even organisms, after considerable physical injury or damage, resulting from pathologies, tumors, congenital diseases or traumas, for example. As a consequence of tissue regeneration, both the composition and the tissue properties are restored, and the newly formed tissue is highly similar to the original tissue. The regenerative capacity is directly related to the presence of stem cells or progenitor cells, which are capable of proliferation and differentiation [4,5]. Tissues that maintain a high proliferative capacity, such as the hematopoietic system, have regenerative capacity even in adult organisms [6].
Cell proliferation occurs in repair processes in general, accompanied by intense production of extracellular matrix, with large amounts of collagen, resulting in the formation of fibrous tissue to occupy the injured area. Although there is lesion filling, both the composition and the tissue properties are different from the original tissue, and the tissue organization pattern is not restored, leading to an altered performance of its functions [2]. Skin healing processes with the presence of scars are examples of tissue repair [3].
Besides the natural processes of regeneration and repair, it is possible, through medical intervention, to fill lesions with natural or synthetic materials, aiming at the recovery of the compromised area, and conferring certain properties to the tissue, avoiding, for example, exacerbation of the initial lesion or the evolution of degenerative processes [1,7].
The three approaches can be used in tissue engineering, targeting regenerative medicine, as they allow the recovery of compromised areas in different degrees. However, the primary objective is regeneration, recomposition of the original tissue and resumption of the biomechanical and molecular properties, with the normal performance of their functions [1,7-8].
Tissue regeneration involves cell recruitment, growth, proliferation and differentiation, with the latter representing a crucial stage for the success of regeneration, avoiding the formation of fibrous tissue characteristic of the repair [9-12]. Tissues with greater regenerative capacity, such as the skin and liver, intrinsically present cells able to migrate to occupy the affected region, and the same cells maintain the proliferative capacity, enabling occupation of the lesion [3]. In other tissues the regenerative capacity is even more impaired. In the cartilage, for example, the cells remain embedded in the extracellular matrix, and the absence of blood vessels inhibits the presence of other types of component cell in the tissue; even the cell migration and proliferation processes are compromised. In general, regeneration and repair processes do not occur naturally in these cases, requiring surgical intervention to stimulate the subchondral bone marrow, thus enabling the presence of cells capable of tissue repair in the compromised area [13]. Other scientific techniques and methodologies seek alternatives to enable the processes both of repair and of tissue regeneration [9-12,14-16].
Anyhow the final stage of the abovementioned processes, cell differentiation, is critical. An understanding of the mechanisms that lead to the differentiation process in adult organisms allows the proposition of improvements in existing technologies and of alternatives geared towards the optimization of guided tissue regeneration processes, in regenerative medicine.

Explanation:
Is the Amazon Rainforest Resilient or Fragile to change and why?
I thought Resilient because the rainforest has changed over time because it was fragile before.
Answer:
Resilient.
Explanation:
Amazon Rainforest is more Resilient to change because Amazon rainforest has evolved over millions of years. Amazon rainforests may be more resilient to climate change induced by carbon dioxide due to storing a lot of carbon as living biomass. The climate change is unable to change the Amazon rainforest due to their dense vegetation but if the rainfall patterns changes means the Amazon rainforest experience less rainfall due to climate change so it has a change this Amazon rainforests.

Which explanation best describes why sexually reproducing organisms have greater genetic
variation than asexually reproducing organisms?
Helppp
Answer:
think of it this way lol
Explanation:
In asexual reproduction, you are essentially producing clones of the parent. There is no genetic variation between parent and offspring - think of mitosis.
In sexual reproduction, you have several chances for genetic variation. The first occurs in meiosis 1, when homologous pairs line up and crossing over occurs. Then in meiosis 2, different combinations of chromosomes (some from mother, some from father) could end up in the gamete cells. Finally, when the gametes (egg and sperm/spore) come together in fertilization, that represents a brand new combination of chromosomes, and therefore alleles, than either of the parents had.

c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells
d. mutations that cause cancer are specific and cannot be passed on regardless of the type of cell they occur in
Answer:
c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells
Explanation:
just because you're parents smoked and got lung cancer doesn't mean you'll get lung cancer. (unless you're breathing the smoke, but that's different from inheriting it.)
Why are plants like grasse able to
reproduce more quickly than others?
A.) The pollen is able to spread with the wind farther and faster.
B.) The seeds are able to fertilize and grow in the soil at a faster rate.
C.) The root may grow horizontal rhizomes that make new shoots.
Answer:
C.) The root may grow horizontal rhizomes that make new shoots.
Explanation:
Plants like grasses able to reproduce more quickly than others because their roots grow horizontal rhizomes into a new shoots. These grasses spreads in the soil due to movement of rhizomes horizontally and grows its shoot with this movement. This spreading helps the grasses to make carpets in the grounds and has the ability to grow faster than other plants so we can say that growth of horizontal rhizomes is responsible for quick growth of grasses.

Explain the process of photosynthesis in a plant in detail.
Answer:
Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. The chemical energy is then stored as sugar. During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food).
Explanation:
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
Answer:
The roots absorb water and nutrients. Water is carried to the leaf by the xylem in the stem. Carbon dioxide enters the leaf through the stomata. Energy from the sun is captured by chlorophyll in the chloroplasts. The process begins once these three reactants are present. Sunlight provides energy for a series of chemical reactions. Molecules break apart and join with other molecules to form glucose, which is a sugar or food for the plant, and oxygen, which is released into the air.

Answer:
Human beings change resources in two new form like people use natural resources to make buildings, bridges ,machinery and vehicles with the help of technology such resources are called human-made resources. ... Likewise, technology is also a man-made resource. Man-made resources are mostly renewable.
Human made resources are those resources that are created by humans, as opposed to being found in nature. This includes both physical resources like buildings, machines, and tools, as well as intangible resources like intellectual property, knowledge, and know-how. Human made resources are a key factor in economic development and prosperity, and are essential for businesses and organizations of all sizes.

5. When is extinction of a species most likely to occur?
A)when environmental conditions remain the same and the proportion of individuals within the species that lack adaptive traits increases
B)when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce
C)when environmental conditions change and the adaptive traits of the species favor the survival and reproduction of some of its members
D)when environmental conditions remain the same and the proportion of individuals within the species that possess adaptive traits increases
Answer:
Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
The extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
If the members of species do not have adaptive traits to survive and reproduce, they will definitely become extinct in near future.
This is because the relative fitness is directly related to the appearance or existence of particular species in the habitat.
Therefore, the extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.

State two differences between respiration and breathing
Answer:
1. Respiration results in the production of energy and Breathing doesn’t provide energy.
2. Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation while respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.
