Answer:
All living things are composed of cells.
Cells are the basic units of structure and function for living things.
All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

how did the settlers view panther when they came to north America
Answer:
They viewed the Panther with fear and set out on a mission to exterminate it.
Explanation:
The first Spanish conquistador to ever sight a Panther was Alvar Nunez Cabeza de Vaca in 1513. When he saw the panther which he referred to as a lion, he was fearful of the animal. He and other Europeans set out on a mission to exterminate all Panthers. This was also necessary as they had to clear the bushes for them to reside.
In 1821 when Florida officially became a part of the United States, and people had to relocate there, a $5 dollar bounty was placed on every Panther killed. The Panthers relocated farther into the wild. As of 1990, the population of the Panther was just around 50. Panthers have since been named an endangered species.

How does weathering affect Earth's surface?
Answer:
Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock. An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger.
Explanation:
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.

Identical haploid daughter cells are produced from diploid parent cell.This process is required to produce egg and sperm cells for s exual reproduction.What is meiosis?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for s exual reproduction.Cell division occurs twice during meiosis, one starting cell can produce four gametes.In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.To know more about meiosis here

Eukaryotic genomes have gene sequences that can code for more than one polypeptide sequence because _____.
Answer:
The correct answer would be -A pre-mRNA becomes mRNA by cutting out different introns
Explanation:
During the process of the RNA splicing, pre-mRNA has several specific segments of sequence that are identified by the spliceosome and then removed from the pre-mRNA. Specific parts that are removed are known as introns and the parts that stuck to become mRNA are exons.
Gene sequences in the eukaryotic genome can code for more than one protein due to removing the different introns every time to become mRNA from pre mRNA.

what cause asexual reproduction
Answer:
It is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
The offspring that are produced by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent and thus have the sane identical identities of the parent.

An individual is heterozygous for a gene at a specific locus. ________ will have the same form of alleles at that locus after S phase.A. Sex chromosomes.B. Homologous chromosomes.C. Non-sister chromatids.D. Sister chromatids.
Answer:
D
Explanation:
Sister chromatids will have the same form of alleles at the locus after S phase.
This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.
The correct option is D.
An operon in E. coli called the Gua operon, encodes proteins responsible for guanine biosynthesis. Two genes, guaA and guaB are under the control of a single promoter and operator, similar to the arrangement in the lac and trp operons. A repressor protein, purR, binds to the operator. In what conditions (high guanine or low guanine) do you suppose this repressor binds to the operator? Do you consider this a "repressible" or "inducible" operon? 3 pts
Answer:
Hight guanine"Repressible" operonExplanation:
An operon is a fragment of DNI with genes that encode for different proteins of metabolic vias. Operons are composed of a regulator gene (that codifies for the repressor), the operator region (that links with the repressor protein), and the promotor sequence (RNA polymerase recognizes the promotor where it begins the RNA synthesis).
The repressor deactivates the expression of a gene when binding the operator of that gene. This binding does not allow the production of mRNA, and hence, proteins that this molecule should synthesize.
This protein has a negative effect on genic expression impeding the transcription of RNA from DNA.
Operons might be inducible or repressible. When the operon is inactive, and a little inductor protein activates it, then the operon is inducible. On the contrary, the repressible operon is the one that is normally active, but the little corepressor protein inactivates it.
During high guanine concentration, the repressor protein must act to regulate the amount of guanine in the environment. Hence it links the operator of genes guaA and guaB to stop the biosynthesis. The operon was initially active, but then by the union of the repressor, it gets inactivated. This is a "repressible" operon.SOMEONE PLZ HELP!!!!!!!!

Darren used the following soil triangle to identify a sample of soil as sandy loam.
Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.
Which description of soil likely allowed Darren to make this identification?
Mostly large particles, with a gritty texture, 60% sand, 10% clay, and 30% silt
Mostly large particles, with a smooth texture, 40% sand, 50% clay, and 10% silt
Mostly small particles, with a smooth texture, 10% sand, 50% clay, and 40% silt
Mostly small particles, with a smooth texture, 30% sand, 30% clay, and 40% silt
Answer: I'm not sure but i think it's Mostly small particles, with a smooth texture, 10% sand, 50% clay, and 40% silt
Explanation:
Soil Texture is defined as the proportion of sand, silt, and clay-sized particles, which make up the composition of the soil.
The description that matches Darren's identification is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.
The soil texture can be explained as:
1. Clay in soil texture refers to the mineral soil particles that are less than 0.2 millimeters in diameter. Clay soil is 40% or more clay, less than 45% sand, and less than 40% slit.
2. Silt in the soil texture has a high percentage of sand and it feels smooth, having smooth textures. This soil has a high percentage of clay.
3. Sand is the largest mineral particle, which consists of the coarsest particles. The particles feel gritty and have a diameter of about 0.05 to 0.002 mm.
Thus, the correct answer is Option C.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.
