Answer:
variegated female x green male
Explanation:
The four o'clock (Mirabilis jalapa) plant is a common ornamental species of Mirabilis (clade Angiosperms, flowering plants) whose leaf pigmentation is a well-known case of maternal inheritance. Moreover, chloroplasts are organelles that have their own genome which follows a maternal inheritance pattern in the majority of plant and animal species because they are contained in the cytoplasm (i.e., chloroplast DNA is inherited only from the mother because only the maternal cytoplasm persists after fertilization). Thus, chloroplast DNA has an inheritance pattern that challenges Mendel's Laws of inheritance (i.e., distinct from nuclear DNA). In the case of the four o'clock plant, the genes responsible for leaf color are located in the chloroplast genome and therefore these genes are transmitted from the female parent to the progeny. In this case, the leaf variegation is caused by two different types of chloroplasts that are inherited from the mother: normal green chloroplasts and defective chloroplasts (without chlorophyll pigment).

What are the REACTANTS in photosynthesis?
[A] Carbon dioxide (CO2), water (H2O), and ATP
[B] Carbon dioxide (CO2), water (H2O), and sunlight
[C] Glucose (C6H12O6) and oxygen (O2)
Answer:
[tex]\boxed {\boxed {\sf B. \ Carbon \ dioxide , water, and \ sunlight}}[/tex]
Explanation:
The reactants are the substances that go into a reaction. You begin with the reactants, then the reaction turns them into different products.
Remember, photosynthesis is a process that certain organisms, like plants, algae, and some types of bacteria, undergo to create "food". They actually produce glucose which serves as an energy source because it is converted into ATP during cellular respiration.
The formula for photosynthesis is:
[tex]6H_2O+6CO_2+ light \ energy \rightarrow C_6H_12O_6 + 6O_2[/tex]
or
[tex]water + carbon \ dioxide + light \ energy \rightarrow glucose + oxygen[/tex]
The reactants are the starting substances, so they are to the left of the arrow. Therefore, the reactants are carbon dioxide (CO₂) water (H₂O), and sunlight. Choice B is correct.
What are the PRODUCTS in photosynthesis?
[A] Carbon dioxide (CO2) water (H20), and ATP
[B] Carbon dioxide (CO2), water (H20), and sunlight
[C] Glucose (C6H12O6) and oxygen (O2)
How does sexual reproduction bring about variation
Answer:
The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.

Explain why serine proteases do not catalyze hydrolysis if the amino acid at the hydrolysis site is a D-amino acid. Trypsin, for example, cleaves on the CC-side of L-ArgArg and L-LysLys, but not on the CC-side of D-ArgArg and D-LysLys.
Answer:
Explanation:
A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.
SEE BELOW FOR THE APPROPRIATE STRUCTURES.
We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.
The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.
Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.

“Scientist have long understood how nutrients move from the oceans surface to its depths. As phytoplankton die, they sink and collect on the ocean floor. But if nutrients are continually sinking to the depths of the ocean, how are surface waters replenished with nutrients? Scientist discovered that in certain regions of the ocean, the nutrients-rich deep water was upwelling, or rising to the surface”
which phrase from the paragraph helps you to understand that ocean health involves steady restoration
Answer:
"As phytoplankton die,they sink and collect on the ocean floor"......."scientist discover that in certain regions of the ocean the nutrients deep water was rising to the surface"
Explanation:
this shows steady restoration of ocean nutrients
As seen that the death of planktons lead to uprise in oceanic nutrients .the cycle just keeps going on and on

Nuclear hormone receptors form a complex with their ligands, other proteins, and DNA control elements in order to regulate the expression of specific genes. These nuclear hormone receptors have four principal domains. Categorize each trait according to the appropriate nuclear hormone receptor domain with which it is associated.
Answer:
Explanation:
Nuclear receptors are a type of protein that functions as an intracellular steroid and thyroid hormone receptor. The interaction of these hormones in conjunction with nuclear receptors changes the pattern of gene expression, allowing certain genes to be transcribed while others are silenced.
As a consequence, unique mRNA translation products, proteins, and, in most cases, enzymes are generated. Nuclear receptors connect to DNA directly and control the expression of certain genes, regulating the organisms growth, homeostasis, and metabolism.
The following domains are found in a normal nuclear receptor:
The amino-terminal activation domain contains the transcriptional activation mechanism and is strongly variable in sequence (AF1). The recruiting of coregulators is the domains key feature.
⇒ Activation function 1 (AF1); Coregulator recruitment
DNA binding domain: It is amongst the most closely conserved centrally located domains, with two zinc fingers that attach to specific DNA sequences known as hormone reaction components (HRE).
⇒ nine conserved cysteine residues; zinc finger domain; center of the receptor.
The hiinge domain serves as a versatile connection between the DNA binding and ligand-binding domains. It has a nuclear localization signal in it. ⇒ Nuclear localization signal
Ligand binding domain: The sequence of the ligand-binding domain is moderately conserved throughout nuclear receptors. It denotes the carboxyl-terminal end of a ligand domain. It has hydrophobic steroid-binding pockets that draw the hormone and AF2 activation domains. It also attaches to proteins that serve as coactivators and corepressors.
⇒ binding of corepressor proteins; steroid-binding hydrophobic pocket; AF2 activation domain; binds coactivators; carboxyl-terminal end
If a region on earth has a TEMPERATE climate, which of the following
statements will be true about that region?
O The temperature is usually warm and it rains often.
O
The temperature is usually cold and it rains or snows often.
The temperature and rainfall change at different times of the year.
The temperature is usually cold and there is very little rainfall.
Answer:
The temperature and rainfall change at different times of the year.
Explanation:
A temperate climate region is a territory in which the climate cannot be classified as completely hot or cold, nor rainy or dry, but these characteristics are variable according to the season of the year in which it is found. Thus, these climates do not have extreme heat or cold temperatures, but rather moderate climatic conditions. An example of a region with a temperate climate is the Mediterranean region, the State of Georgia in the USA or Uruguay.

The sequence of DNA ACTGGGCGTAAG part of a gene. How many CODONS can be found in the segment
Explanation:
First, think about which base pairs arise in complementary strands of DNA:
DNA → DNA
adenine → thymine (A → T)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
DNA → RNA
adenine → uracil (A → U)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
Giving us the corresponding sequence:
g In the mid-1800s, overhunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _________, which makes it more susceptible to ___________.
Answer:
In the mid-1800s, over-hunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _bottle neck event (genetic drift)_, which makes it more susceptible to _developing a genetic disease_.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect- . The bottleneck effect most likely affects smaller populations.
In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered to a current population size of 100,000 individuals, but the genetic pool might have not. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and increase the probability of developing a genetic disease.
