the chromosomal hereditary material is packaged in this organelle in eukaryotic cells but not in prokaryoitc cells. This organelle is called
Answer:
Nucleus
Explanation:
The correct answer would be the nucleus.
The nucleus is a double membrane organelle that is found in all eukaryotic cells but not in prokaryotic cells. It contains the chromosomal hereditary material of eukaryotic cells and serves as the control center of the cell where other cellular activities are dictated.
The chromosomal hereditary materials of prokaryotic cells lie freely within the cytoplasm unlike what is obtainable in eukaryotic cells. The materials are package in a condensed fashion within the eukaryotic nucleus to form a structure known as chromatin. During cell division, the chromatin decondenses and become visible under the microscope as chromosomes.

Explanation:
Sickle cell anaemia is an inherited autosomal recessive
condition caused by a mutation in the haemoglobin
subunit beta (HBB) gene. A male and female who are
phenotypically normal, discover through genetic testing
that they are both carriers of a HBB mutant allele. What is
the probability that their first child will be biologically
female and phenotypically normal?
Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene locus to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)

The organs found in plants or animals is stem vascular. Therefore, option (D) is correct.
What are the features of the stem vascular?A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients.
The vascular system of plants, complete with xylem and phloem, fills both purposes. Stems, along with roots, also store food for the plant. Pith, a tissue that lies in the center of the stem.
A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem.

What happens to a population when immigration increases?
A. The population size usually increases.
B. The emigration rate usually increases.
O C. The emigration rate usually decreases.
O D. The population size usually decreases.
Answer:d
Explanation:
When immigration increases, the population size usually increases, as shown in Option A, as immigration is the movement of individuals into a population from another population.
What is immigration?Immigration is the movement of individuals from one population to another. It involves the addition of new individuals to the population, which can increase its size. When more individuals enter a population, they bring with them new genes and genetic diversity, which can enhance the adaptive potential of the population. This can help the population better withstand environmental challenges and increase their chances of survival, but increased immigration can also have negative consequences. For example, it can lead to competition for resources among individuals, which can lead to a decrease in the quality and availability of resources for the population as a whole.
Hence, when immigration increases, the population size usually increases, as shown in Option A.

Snake venom contains a mixture of enzymes, which include phospholipase that break down cell membranes, proteinases that destroy proteins, as well as amino acid oxidases and nucleotidases that break down the monomers for protein and DNA synthesis, which is why they can be so deadly. If you were bitten by a venomous snake you may be treated with an antivenom. In addition to antibodies that help your immune system recognize and fight the foreign molecules, what else does the antivenom most likely contain
Answer:
The correct answer is - Venom enzyme inhibitors.
Explanation:
The snake venoms are the complex mixtures of phospholipase A2s, disintegrins, serine proteases, C-lectins, and metalloproteases, and others. The snake venom phospholipase A2s (svPLA2s) enzymes found in most of the families of venomous snakes that cause anticoagulant effects, cardiotoxicity, neurotoxicity, and cytotoxicity, and other effects.
In antivenom, there are Venom enzyme inhibitors other than antibodies that help in neutralizing these enzymes by weakening or inhibiting these toxic actions.

The RNA product of the genetic code above has the sequence ____________ . It binds to the small subunit of the ____________ . It is joined by the large subunit, completing the initiation stage of the process of ____________ .
The Genetic code was not given, however, The genetic code associated with this question is as follows:
ACCGCTTGCCGCAAT
Answer:
The correct answer is - UGGCGAACGGCGUUA, ribosome, translation.
Explanation:
The translation is the second process of protein synthesis followed by transcription. Transcription produces mRNA sequence from DNA gene sequence and bring it to the cytoplasm for translation to take place.
The gene segment ACCGCTTGCCGCAAT is encoded to mRNA sequence by converting bases to their complementary bases A to U and C to G and G to C and T to A so the new code will be - UGGACGAACGGUGUUA.
This mRNA binds with a small subunit of ribosomes and then a large subunit of ribosome joined and completes the first stage initiation of the translation.

4. Many commercial grow lights deliver light mostly in the yellow/red part of the spectrum, along with smaller portions of all other visible light. Why would a grow light such as this promote plant growth and reproduction (flowering and fruiting) or is this a con job?
Answer and Explanation:
These lights can, in fact, promote the growth and reproduction of plants.
This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.
Choose the statement about renewable and nonrenewable energy sources that is NOT true.
a. Renewable energy creates little or no waste and has few negative environmental impacts.
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
c. Most nonrenewable energy sources can be renewed, but it takes thousands to millions of years for them to form.
d. New technologies promise future increases in the use of renewable energy sources.
Answer:
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
Explanation:
Fossil fuels have had tremendous negative impacts on the environment and humans as well. For that reason, the use of renewable sources of energy, such as hydropower and biomass, have become increasingly popular over the last few decades.
Within our lives, or possibly within many, many lifetimes, the sources of non-renewable energy will run out or cease to exist. The three main fossil fuels that are used as non-renewable energy sources are coal, oil, and natural gas. Carbon is the main element in fossil fuels. Thus, option B is correct.
What best define about nonrenewable energy sources?Fossil fuels have had a terrible impact on both the environment and people. Because of this, the usage of renewable energy sources, such as biomass and hydropower, has risen in popularity over the past few decades.
A natural resource is classified as non-renewable (also known as finite) if it cannot be easily replenished by natural processes at a rate fast enough to keep up with use. Carbon-based fossil fuels are one illustration. The original biological substance can change into a fuel like gas or oil thanks to heat and pressure.
Therefore, There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
