Answer:
C.Use a microscope to observe the shapes of the bacteria.
Explanation:
Bacteria is a type of pathogenic micro-organisms. They are mostly known to cause diseases and can be viewed using an electron microscope.
Bacteria have different shapes and colors. The shapes include bacilli(rod shaped), cocci(spherical)or spirilla( twisted).
The most useful strategy will be to use a microscope to observe the shapes of the bacteria.

Fungi,
Explanation:
How does the Classification system distinguish between organisms?
Answer:
By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.
Explanation:
There are five kingdoms:
Monera: bacteria Protista: amoeba, paramecium, euglenaFungi: yeast, rhizopusPlantae: flowering and non-flowering plantsAnimalia: animals (vertebrates and invertebrates)Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.
Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
A group of scientists is trying to bring mammoths back by modifying elephant DNA. The new animals would have a mixture of elephant and mammoth genes. What will be the effect of the new genes?
A. The new genes will produce different proteins.
B. The new genes will prevent DNA replication.
C. The new genes will require gene therapy.
D. The new genes will not have RNA.
Answer:
C
Explanation:
Because when new genes are created they won't be able to adapt easily, so they will require gene therapy so they will be able to adapt easier.
Hope this helps you. :)
Have a good day!
The new genes will produce different proteins. Therefore, option (A) is correct.
By modifying the DNA of elephants to include mammoth genes, the scientists aim to introduce genetic variations that were present in the woolly mammoth. These genetic variations would result in the production of different proteins compared to the proteins produced by elephants.
Proteins are essential molecules that perform a wide range of functions within living organisms, including structural support, enzymatic activity, and regulation of biological processes. Therefore, the introduction of new genes from mammoths would lead to the production of different proteins, potentially affecting various traits and characteristics of the modified elephants.

Environmental agencies throughout the world believe that humans have forced Earth out of its natural cycle. Consider the choices below as possible sources of empirical evidence for anthropogenic climate change. Which choice does not support this view?
Answer:
Human activities increases the concentration of oxygen in the atmosphere.
Explanation:
Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

Excretory
Digestive
Answer: Produces Urine- Excretory
Large intestine- Digestive
Ureters- Excretory
Mouth- Digestive
Filters blood- Excretory
Absorbs Nutrients- Digestive
The organs can be matched as Excretory system: produces urine, have ureters, filters blood. Digestive system: have large intestine, mouth and absorbs nutrients from food.
What is body system?An organ system is a biological system made up of a collection of organs that collaborate to perform one or more functions.
Each organ in a plant or animal body serves a specific function and is made up of distinct tissues.
The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids to help maintain internal chemical homeostasis and prevent body damage.
The gastrointestinal tract, as well as the digestive organs, comprise the human digestive system.
Digestion is the process of breaking down food into smaller and smaller components so that it can be absorbed and assimilated by the body.
Thus, excretory system is related to urine production, have ureters, blood filtration, while digestive system includes large intestine, mouth and absorbs nutrients from food.

The homologous chromosomes form pairs.
Chromosomes line up in the middle of the cell.
Chromosomes condense or shorten up before cell division begins.
Answer:
It's B
Explanation:
"The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

How can a mutation that causes a change in the structure or function of a protein be beneficial to an organism?
Answer:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression.
Explanation:
Mutations can result in structural alterations in a gene's translation, as well as a decrease or complete loss of the gene's function.
Because a change in the DNA sequence affects all copies of the encoded protein, mutations may be extremely detrimental to a cell or organism.
Genes have a crucial part in an organism's development and function. Mutations can result in structural changes in the decoding of a gene, as well as a decrease or complete loss of its activity.

Which molecules are easily diffuse across the plasma membrane
Answer:
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

If a muscle cell of a typical organism has 32 chromosomes, how many chromosomes will be in a gamete of that same organism?
A) 8
B) 16
C) 32
D) 64
B
Explain how the random alignment of homologous chromosomes during metaphase I contributes to variation in gametes produced by meiosis.
Random alignment leads to new combinations of traits. The chromosomes that were originally inherited by the gamete-producing individual came equally from the egg and the sperm. In metaphase I, the duplicated copies of these maternal and paternal homologous chromosomes line up across the center of the cell to form a tetrad. The orientation of each tetrad is random. There is an equal chance that the maternally derived chromosomes will be facing either pole. The same is true of the paternally derived chromosomes. The alignment should occur differently in almost every meiosis. As the homologous chromosomes are pulled apart in anaphase I, any combination of maternal and paternal chromosomes will move toward each pole. The gametes formed from these two groups of chromosomes will have a mixture of traits from the individual’s parents. Each gamete is unique.
In what ways is meiosis II similar to and different from mitosis of a diploid cell?
The two divisions are similar in that the chromosomes line up along the metaphase plate individually, meaning unpaired with other chromosomes (as in meiosis I). In addition, each chromosome consists of two sister chromatids that will be pulled apart. The two divisions are different because in meiosis II there are half the number of chromosomes that are present in a diploid cell of the same species undergoing mitosis. This is because meiosis I reduced the number of chromosomes to a haploid state.
