Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Which reason best explains why dead specimens must be used with transmission electron microscopes?
A.) Electrons pass over the specimen.
B.) The lights that are used are harmful to the specimens.
C.) Specimens are placed in a vacuum.
D.) The image that is produced is two dimensional.
Answer:
C. Specimens are placed in a vacuum
Answer:
C. Specimens are placed in a vacuum
Explanation:
Since transmission electron microscopes must be used in a vacuum the specimen cannot be living. In a vacuum, there is no oxygen so nothing could survive it.
How does altitude affect climate patterns in a region? Areas at high elevations have cooler temperatures. Air continues to warm as it rises to a higher elevation. Tropical regions do not have many differences in altitude. High-altitude areas have less variation in seasonal temperatures.
Answer:
A. Areas at high elevations have cooler temperatures.
Explanation:
Areas with high altitude or elevations have cooler temperatures because air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."

Can an organism function with a faulty organ system?
Answer:
All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Explanation:
Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive

Which scenario breaks the law of segregation? a gamete contains the father’s allele the gametes produced each have 1 allele after meiosis II a gamete produced has 2 of the same alleles after meiosis II the gamete fertilized has the dominant trait
Answer:
The answer is c a gamete has two of the same alleles after meiosis 2
Explanation:
I took the test
The scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".
LAW OF SEGREGATION:
The law of segregation as proposed by Gregor Mendel states that the alleles of gene will separate into gametes after meiotic division. The separation occurs in such a way that each gamete have only one allele of a gene after meiosis. For example, if a gene Aa undergoes meiotic division, the law of segregation explains that each gamete will contain either A or a in an equal proportion. Based on the law of segregation, two alleles of a gene cannot be present in each gamete after meiosis II. Therefore, the scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".Learn more: https://brainly.com/question/235475?referrer=searchResults
Which diagram correctly shows how heterozygous alleles are found on homologous chromosomes?
Answer:
The answer is I think D
Explanation:
The diagram that correctly shows how heterozygous alleles are found on homologous chromosomes is ; Aa ( The first diagram )
Heterozygous alleles are different alleles gotten/inherited from the genes inherited from each parent cells ( i.e. from each parent ). while
Homologous chromosome is a pair of chromosomes containing same gene sequence, chromosomal length and posses the same centromere location in each chromosome in the pair.
Hence we can conclude that The diagram that correctly show how heterozygous alleles are found on homologous chromosomes is the first diagram ( Aa ).

Which is an organelle that performs photosynthesis and is paired with its correct function?
A) Chloroplast-converts light energy into chemical energy.
B) Chloroplast-converts chemical energy into light energy.
C) Mitochondrion-converts cellular energy into glucose chemical energy.
D) Mitochondrion-converts energy found in glucose into energy for cells.
Answer:
A
Explanation:
Plants absorb the light and turn it into chemical energy with the help of chloroplasts
Chloroplast is the organelle in the plant cell which converts light energy into chemical energy. Chloroplast performs photosynthesis. Thus, the correct option is A.
What is Chloroplast?A chloroplast is a type of membrane-bound organelle which is known as a plastid which conducts photosynthesis mostly in the plant cells and algal cells. Chloroplast are the organelles which convert the light energy into chemical energy in the form of carbohydrates (sugar). The photosynthetic pigment chlorophyll is present in the chloroplast which captures the energy from sunlight, converts it, and stores it in the energy-storage molecules such as ATP and NADPH while freeing up the oxygen molecule from water in the cells.
Chloroplast is the double membranous organelle which is present in the plant cells and certain algal cells. This organelle is absent in the animal cells. Thus, they cannot perform photosynthesis.
Therefore, the correct option is A.

How does the use of wild-life/animals impact on the earth?
Answer:
Hope it helps...
Explanation:
Animals help us to save our environment. Some micro organisms such as bacteria help us clean the environment; others help plants by converting free nitrogen from air and feeding the roots. Some insects and earthworms help in agriculture by increasing fertility of the soil and also by increasing organic quality of soil.
