Answer:
A. It will most likely rain because cool air cannot hold as much moisture as warm air.
Explanation:
The humid climate is actually damp and very hot. As the weather is humid and hot, it will most likely rain as cool air cannot hold as much moisture as warm air.
What is the meaning of humid?Humid means it contains perceptible moisture as the weather is very hot.
A high humidity level always has warmer air, as it can hold more water at a higher temperature.

A phycologist is interested in testing the claim that the proportion of algae from a local rivulet that belonged to the particular phylum cyanobacteria is at least half. A random sample of 50 alga was obtained and each alga was categorized as either being cyanobacteria or not. It was found that 38 were, in fact, cyanobacteria. The test statistic for this hypothesis test is...
Answer:
The test statistic for this hypothesis test is - 3.68.
Explanation:
A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
Sample proportion = 38/50
= 0.76
Hence,
Test statistic
[tex]= \frac{0.76-0.50}{\sqrt{0.50*0.50/50}}[/tex]

Mode of Action of the Herbicide DCMU When chloroplasts are treated with 3-(3,4- dichlorophenyl)-1,1-dimethylurea (DCMU, or diuron), a potent herbicide, O2 evolution and photophosphorylation cease. Oxygen evolution, but not photophosphorylation, can be restored by addition of an external electron acceptor, or Hill reagent. How does DCMU act as a weed killer
Answer:
It acts as a weed killer by blocking photosynthesis
Explanation:
Photosynthesis is important to plants because it is their principal form of energy.
When DCMU is introduced to weeds, what it does is to block or slow down the process of photosynthesis. Carbon dioxide fixation is slowed down causing weeds to die off. DCMU strongly slows down photosystem II. When this is done, lipid and protein membranes would get destroyed and the weed cells would begin to dry and shed off

thankshope it helpsEarly genetic manipulation of petunias included an attempt to engineer dark purple petals. To this end, extra copies of the gene that causes purple pigment was engineered to be produced in the petunia. However, to the surprise of many, the plants carrying the extra copies of the purple gene were completely white or only had patches of color. Molecular analysis revealed that the purple gene was reduced 50-fold in the engineered plants compared to wild type. Provide a possible explanation how this occurred. Also, provide a possible experiment that may overcome this setback
Answer:
The altered pigmentation in transgenic petunia plants is caused by the RNA interference (RNAi) mechanism
Explanation:
The RNA interference mechanism is a naturally occurring mechanism by which single-stranded RNA molecules can bind to complementary mRNAs in order to inhibit gene expression, blocking translation and leading to mRNA degradation. The example above described is a classical genetic experiment (Napoli et al. 1990 ) that showed the existence of the RNAi pathway by the overexpression of a chimeric chalcone synthase (CHS) gene in pigmented petunia flowers, which blocked anthocyanin biosynthesis. In this experiment, irregularly bicolored/white flowers in transgenic petunias containing exogenous pigmentation genes were developed. The co‑suppression of gene expression was produced by the high-copy-number transcription of the CHS transgene, showing the existence of an undescribed RNAi silencing mechanism. Somatic reversion of the altered phenotype can be achieved by restoring the normal mRNA levels for these pigmentation genes, e.g., by a progeny testing in order to eliminate transgenic CHS expression.

Answer:
a. The gastrodermis contains various cell types and develops from the endoderm during development.
d. The epidermis is associated with sensing the environment and prey capture.
Explanation:
Most cnidarians have two layers of cells organized into some luck of tissues that have specific functions.
Cnidarians' body organization is simple: It is a hollow structure composed of two cellular layers: epidermis, which is the external layer, and gastrodermis that is the internal layer, formed by lining cells in the gastrovascular cavity. Between these two layers, place the mesoglea that varies from a thin non-cellular membrane to a mucous, fibrous, thick membrane with amebocytes.
Epidermis and gastrodermis originate from two embryonic tissues, the ectoderm, and the endoderm, respectively.
The epidermis has five types of cells with different functions: epitheliomuscular, interstitial, cnidoblasts, secretors, and sensorial.
Gastrodermis is composed of cells such as nutritive cells, glandular enzymatic cells, secretory cells, and sensory cells.

O adapting
O cloning
O genetic engineering
O selective breeding
Answer:
selective breeding............
Genetic engineering allows the modification in the DNA of an organism. To obtain a disease free plant, genetic engineering is carried out. Thus, option c is the correct answer.
What is genetic engineering?Genetic engineering is a tool used in biotechnology to bring modifications or alterations in the genetic material - DNA of an organism. It modifies the DNA through addition of a gene segment or deletion of a gene.
In genetic engineering process, a specific gene of interest or the desired genetic sequence is selected. It then inserted into a cloning vector to allow its replication in the host gene. The so called 'recombinant' then formed is inserted into the host through various insertion techniques.
Genetic engineering thus allows the selection of a disease free plant, pest resistance or temperature resistant plant. A new variety of the plant can be obtained through genetic engineering.
The genome of an organism can thus be edited where the unhealthy genes can be eliminated through genetic engineering.

What the consequences would be if the entire water surface was covered with water lilies
Answer: There can be a ton of damage done if water lilies overgrow.
Explanation:
Water lilies protect the organisms under the body of water and provide shade to the plants and organisms underneath. These are very important for organisms, as they also provide a place to rest. But if the entire water surface were to be covered with water lilies, this would be a major problem, because sunlight would have no way of reaching below the surface, and this would decrease oxygen levels for plants and organisms. Without air and sunlight, plants will start to die and organisms of the body of water will also start to die because of no air to breathe. Also, overgrowth of water lilies causes water stagnation and leads to excessive algae blooms. The stagnant water attracts insects like mosquitoes, cockroaches, termites, and more pests which can harm plants and organisms.

Explanation:
The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light and
dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
C)
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.
Answer:
A,B,C,F
Explanation:
A, B, C and D all of these statements support the idea that natural selection changes populations, not individuals.
What is natural selection?Natural selection is a process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This leads to changes in the genetic makeup of a population over time, as advantageous traits become more common and less advantageous traits become less common.
Natural selection is driven by environmental pressures, such as predators, competition for resources, or changes in climate. It is a key mechanism of evolution, and helps to explain the diversity of life on Earth and the ways in which different species have adapted to their environments.
