stay safe healthy and happy.g Cells called ________ influence development by controlling the fate of other cells in their local environment
Answer:
Neighboring Cells
Explanation:
Neighboring Cells are known to be the type of cells that influence development by controlling the fate of other cells in their local environment.
Typically Neighboring cells through the process often referred to as Induction simply influence the development of other cells nearby or in their local environment. This process of cell influence is either by direct cell-cell contact or through the release of practice chemical signals.
Hence, in this case, the correct answer is "Neighboring Cells."
Suppose we have one true-breeding strain of tomato that produces red fruit. Suppose we also have a true-breeding strain of tomato that produces yellow fruit. We KNOW that a single gene is responsible for fruit color, and that the red allele is dominant to the yellow allele. If you make an F2 cross, what proportion of those fruits would you expect to be yellow
Answer:
1/4 or 25%
Explanation:
Let us assume that the fruit color trait in the tomato is represented by R and r. The dominant color red would be represented by R while the recessive color yellow would r.
If a true-breeding red fruit tomato (RR) is crossed with a true-breeding yellow fruit tomato (rr), the F1 would be thus:
RR x rr
Rr Rr Rr Rr
Since R is dominant over r, all the F1 offspring would produce red fruits with the genotype Rr.
At F2:
Rr x Rr
RR Rr Rr rr
RR and Rr = red
rr = yellow
Hence, the proportion of the F2 offspring expected to be yellow would be 1/4 or 25%.

The major difference in gene regulation between prokaryotes and eukaryotes is that A) eukaryotic and prokaryotic genes are usually grouped for common functions. B) eukaryotic genes regulation requires fewer signals that prokaryotic gene regulation. C) eukaryotic gene regulation is more simplistic than prokaryotic gene regulation. D) eukaryotic genes are arranged individually, while prokaryotic genes are grouped into operons. E) eukaryotic gene regulation tends to require less coordination and integration than prokaryotic gene
Answer:
D) eukaryotic genes are arranged individually, while prokaryotic genes are grouped into operons.
Explanation:
A gene is a specif fragment of DNA that contains the information required for cells in order to survive and reproduce. A gene is used as a template to synthesize an RNA molecule, typically a messenger RNA (mRNA) molecule which is then translated into protein. Structurally, the genes are composed of regulatory regions (e.g., promoter sequences) and coding regions. In eukaryotic cells, genes have a specific structure associated with post-transcriptional modifications of the primary mRNA transcripts (pre-mRNAs), which are processed to yield mature RNAs such as mature mRNAs. Eukaryotic genes are structurally arranged in individual segments of information that first encode specific pre-mRNAs. These eukaryotic pre-mRNAs contain coding regions (exons), which are retained in the final mature mRNA, and non-coding regions (introns), which are removed through RNA processing (alternative splicing). On the other hand, prokaryotic genes are clustered in polycistronic transcription units called operons. A procaryotic operon is a functional unit of DNA consisting of a cluster of genes that share a promoter and terminator sequence. These genes are transcribed together into one long mRNA, and this initial transcript is either 1-translated together in the cytoplasm or 2-processed to create monocistronic mRNAs that are translated individually.
In primrose flowers, the dominant allele of gene K is necessary to synthesize blue flower pigment. Otherwise the flowers are white. Blue pigment synthesis is inhibited by a dominant allele of gene D. In other words, plants with the genotype K-D- will not produce pigment (and their flowers will be white) because of the presence of the D allele. If two dihybrid plants (Kk Dd) are crossed what is the ratio of blue to white offspring in the progeny?
Answer:
3/13
Explanation:
K_ gives blue flower pigment
kk gives white flower
The presence of D, either as K_DD or K_Dd results in white flower
Crossing 2 plants with KkDd genotype:
KkDd x KkDd
Offspring:
KKD_ = 9/16 white flower
KKdd = 3/16 blue flower
kkDD = 3/16 white flower
kkdd = 1/16 white flower
Hence, the ratio of blue to white flower would be 3:13

Match each of the following characteristics with the correct connective tissue. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. ResetHelp : parallel arrangement of collagen fibers. : transports oxygen and hormones. : contains chondrocytes. : stores minerals. : random arrangement of collagen fibers. : cushions and insulates.
Answer:
- Parallel arrangement of collagen fibers: Dense regular connective tissue (CT)
- Transports oxygen and hormones: Bood
- Contains chondrocytes: Cartilage
- Stores minerals: Bone
- Random arrangement of collagen fibers: Dense irregular connective tissue (CT)
- Cushions and insulates: Adipose tissue
Explanation:
The dense regular connective tissue (CT) is a type of connective tissue composed of collagen fibers arranged in a parallel pattern which provides a strong association between tissues (e.g., tendons and ligaments). Conversely, in dense irregular connective tissue, collagen fibers are not arranged in parallel bundles (e.g., the dermis in the skin and lamina propria in the gastrointestinal tract). Cartilage is a type of flexible connective tissue composed of chondrocytes, the unique type of cells in cartilage tissues. Chondrocytes are responsible to produce and maintain the collagen extracellular matrix (ECM) which is composed mainly of collagen and proteoglycans (proteins coated with sugar molecules). Bone is a type of connective tissue composed of cells (i.e., osteoblasts, bone lining cells, osteocytes, and osteoclasts), fibers and ground substance. Bones have many functions including, among others, store minerals (calcium and phosphate), protect internal organs, allow movement, provide internal support, etc. Blood is a type of connective tissue (because blood has a matrix) whose main function is to transport oxygen (O2) and essential substances (e.g., nutrients, hormones, etc) to the tissues, and carbon dioxide (CO2) from the tissues to the lungs. Blood contains two different types of cells: red blood cells (i.e., erythrocytes) and white blood cells (i.e., leukocytes). Finally, adipose tissue is a special type of connective tissue in the subcutaneous layer that helps to cushion and insulate the body (providing insulation from heat and cold). Adipose tissue is composed mostly of adipocytes, which are cells that store energy in the form of lipid molecules.
In a eukaryotic cell in mitotic S-phase, a spontaneous DNA double-strand break occurred due to replication fork collapse. Genetic analysis indicates that the break was repaired by a non-crossover mechanism resulting in a stable genome. The DNA repair process responsible for this outcome was:
Answer: The DNA repair process was called recombination repair.
Explanation: A sister or homologous chromatide is used to generate recombination and be repaired in this sort of cases.
what are the two ways mitosis and meiosis increases genetic diversity?
Answer:
crossing over, and mutations caused during crossing over.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
List and briefly describe the chemical sequence of events in the fight-or-flight response to a threatening situation from the binding of epinephrine at the receptor site to readiness for another situation.
Answer:
Binding taking place at the receptor site
G protein activates in the cell membrane
Conversion of GDP → GTP
Activation of adenylate cycles
Cyclic production of AMP → ADP
Initiation of the desired reaction in regard to the original message
Cyclic restoration of AMP → ATP
Explanation:
The description of the mechanism:
Right off the bat, epinephrine attaches to a molecule called a receptor (beta-adrenergic protein).
G protein, which is found on the inner side of the plasma membrane, is activated when epinephrine binds to it.
The GDP-carrying Alpha subunit of G protein is isolated during activation. After that, the GDP is translated to GTP.
Adenylate cyclase is then activated by GTP.
The only enzyme that can catalyze the transformation of ATP to CAMP is adenylate cyclase (Cyclic adenosine monophosphate). As a result, the CAMP molecule (secondary messenger) is produced.
CAMP stimulates protein kinase A, and the cycle repeats till the glycogen phosphorylase enzyme is triggered.
After that, the cyclic amp is brought back and restored.

B) It has inflorescences. C) It has perfect flowers. D) It has incomplete flowers. E) It has imperfect flowers.
Answer:
A) It has complete flowers.
B) It has inflorescences.
C) It has perfect flowers.
Explanation:
Complete flowers are composed of four structures. From the exterior to the interior, we can name the sepals, petals, stamens, and pistils -also known as carpels-.Inflorescences are branch systems destined for the formation of flowers. They might be more or less delimitated concerning the vegetative parts. They are composed of the main axis known as rachis with bracts. Flowers emerge from the axilla of these bracts. Perfect flowers: Those carrying stamens and carpels.
