Answer:
These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z.
Explanation:
(D) O total number of neutrons and protons
A group of scientists is studying a certain species of mouse. Previous genetic analysis has shown that fur color in this species is controlled by a single gene that has two alleles: a dominant allele (FF) that is associated with dark fur, and a recessive allele (ff) that is associated with light fur. The scientists collected data about a population of these mice to help determine the population's fur color allele frequencies. They found that out of 952 mice in the population, 238 mice had light fur. Assuming that the population is in Hardy-Weinberg equilibrium, which of the following is the number of mice in the population that have the genotype FfF, f?
50
238
476
952
Answer:
476

Explain the relationship between these terms photosynthesis chlorophyll thylakoids chloroplasts
Answer:
In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. GA3P and oxygen are products
Answer:
Photosynthesis occurs in the chloroplasts.
Chloroplasts capture light energy.
Thylakoids can be found inside chloroplasts, where light-dependent reactions occur.
Chlorophyll is found in the thylakoids.
Chlorophyll absorbs light energy.
Chlorophyll is what makes plants look green.

Explain why the amount of water on Earth remains relatively constant?
Answer:
because science
Explanation:
The Sun provides the energy to power the water cycle. When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition.
Linnaeus' classification of life only included two categories: animals and plants. Which three kingdoms did he leave out? ( point)
O Insecta, Fungi, and Monera
O Monera, Bacteria, and Protista
O Fungi, Monera, and Protista
O Bacteria, Insecta, and Protista
Answer:
C
Explanation:
These are the three missing kingdoms
Fungi, Monera, and Protista are the three kingdoms he neglected to mention.
What Linnaeus classification?The Linnaean system is based on similarities in apparent physical qualities. This system is a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The domain, which was just added and is a larger taxon, is smaller than the kingdom. Seven levels make up Linnaeus' hierarchical classification scheme. They are kingdom, phylum, class, order, family, genus, and species, in order of largest to smallest. Linnaeus created a hierarchy for nature in Systema Naturae. He suggested that the entirety of nature may be divided into three big categories known as kingdoms. Animals, plants, and minerals made up these three kingdoms. He categorizes each of these kingdoms.To learn more about Linnaeus classification refer to:

Wha is biology and how it started and what kind of biology is this
Answer:
Basically biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine, and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms

what do you call an organism that has been genetically engineered to contain a gene from a different species?
Answer:
A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.
Explanation:
Answer:
This would be called a transgenic or genetically modified organism.

Which scenario best describes natural selection?
a species of flower develops a gene that results in a more attractive nectar causing more pollinators to be attracted
wheat plants are selected for their ability to produce the most wheat germ
a bacteria exposed to radiation acquires a mutation
a hurricane occurs and kills 70% of the members of a rodent species
Answer: A species of flower develops a gene that results in a more attractive nectar causing more pollinators to be attracted
Explanation: I think it’s that one and sorry if I’m wrong but to me the other choices don’t seem to fit as a hurricane kills 70% isn’t helping any organisms adapted and the other two choices no organisms is adapted but the first, the flowers have to adapt as they develop a new gene and it also affects pollinators
IMPORTANCE OF TRANSPORT MECHANISMS IN CELLULAR PROCESSES.
Explanation:
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell's supply of metabolic energy may be spent maintaining these processes.

Describe an example of how island biogeography principles were used to explain biodiversity changes in areas that were not specifically islands.
Answer:
How Biogeography Affects Biodiversity
Alfred Russel Wallace, Father of Biogeography
Figure 1: Alfred Russel Wallace, Father of Biogeography
Some places contain more species than others. For example, Antarctica has fewer species than a temperate deciduous forest, which in turn has fewer species a tropical rainforest. For over 150 years, researchers have sought to make sense of the gross and fine scale spatial patterns in biodiversity, and to elucidate both the proximate and ultimate causes for these patterns.
This article describes some of the major geographic patterns in species richness, and the processes and theories that are thought to account for these patterns. Much of this knowledge has emerged from the tremendous body of work from one scientist, Alfred Russel Wallace (Figure 1), widely regarded as the “Father of Biogeography.” Aside from co-originating the process of Natural Selection with Charles Darwin, Wallace spent extended periods studying the distribution and diversity of plants and animals in Amazonia and Southeast Asia in the mid 1800s. Many of the patterns and processes featured in this article were initially described by Wallace, and careful study of his work indicates that his ideas presaged many of the discoveries made by his numerous successors.
Many of the spatial patterns in biodiversity are overt, others are subtle and yet additional patterns remain undetected. While the existence of these patterns may be obvious — and changes in the environment that are paired with these patterns may also be obvious — the mechanisms that cause the differences in biodiversity along environmental gradients are under still the subject of scientific debate. Because large-scale patterns are the emergent result of complex interactions at many spatial and temporal scales, no single answer is likely to ever emerge, but with continued research our understanding of the processes shaping these patterns increases.
Historical Processes Affecting Biogeography
Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
Figure 2: Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
All species occurring in at a given place and time either arrived from another place or originated in that location from ancestral species. This fact applies to extinct species that were ancestors of all extant species. Species richness in a given location is the result of three factors — the rate of speciation, the rate of extinction, and the dispersal of species from other locations. In principle, if biogeographers could understand how the current and past environment has shaped these three factors, we would then obtain a comprehensive understanding of what generates all biogeographic patterns of species richness. However, numerous environmental and organismal parameters can drive these historical factors, in both complex and interacting fashions.

Answer:
All real numbers
Explanation:
Step 1: Apply distributive property.
[tex](-2)(x) + (-2)(3) = -2x -6[/tex] [tex]-2x - 6 = -2x - 6[/tex]Step 2: Add 2x to both sides.
[tex]-2x - 6 + 2x = -2x - 6 + 2x[/tex] [tex]-6 = -6[/tex]Step 3: Add 6 to both sides.
[tex]-6 + 6 = -6 + 6[/tex] [tex]0 = 0[/tex]Therefore, the answer is all real numbers.
