The amount of light, pressure, and temperature are examples of?
Explanation:
The answer is No. You know light from Stars travel in cold temperature of space and different pressure as they enter our planet after travelling many light year to reach us at the same the speed.
Light bends when entering a different medium(refraction). Even if the medium is same and the temperature is different it will get bend. As the 2 different temperature air behave like 2 mediums (Due to distribution of atoms ).
But light doesn't’ bend by heating or by putting pressure on it.
the development of lateral roots is intiated by the the cork or periderm
Answer:
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).

Why can matter be weighed?
O A. It has mass.
O B. It has width.
O c. It has volume.
OD. It has pressure.
Answer:
A. It has mass.
C. It has volume.
Explanation:
The matter has both Mass and volume.
Mass and volume are two units used to measure objects. Mass is the amount of matter an object contains, while volume is how much space it takes up.
Hope it is helpful...4. A bacterium is discovered with new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but produces hydrogen gas instead of NADH. a. Write a balanced equation for the new reaction. b. What affect does this mutation have on the amount of ATP produced from one glucose molecule
A bacterium is discovered with a new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but makes H₂; the reactant is isocitrate, and the product is alpha-ketoglutarate. As the proton count decreases, less ATP is produced.
What is the importance of the proton gradient in energy production?The proton gradient is formed during the electron transfer chain (ETC) by using all the NADH and FADH₂ that are derived from the glycolysis and kreb cycle. NADH and FADH₂, for example, are two compounds that travel through the different complexes to create the proton gradient, which later produces ATP; however, when H₂ is produced instead of NADH, less of a proton gradient is formed, and thus less ATP is produced. The equation is isocitrate+ NAD+ → alpha-ketoglutarate +CO₂ + H+
Hence, the reaction is composed of substrates isocitrate, NAD+, and products alpha-ketoglutarate, CO₂, and a proton (H+), which will be formed with significantly less ATP than the normal ATP produced from the one glucose.

The owners of a local bakery ask for your help in improving a special yeast strain they use to make bread. They would like you to help them design experiments using RNA interference to turn off genes, to allow them to test their hypothesis that certain genes are important for the good flavors found in their bread. Of the components in the following list, which is the most important to check for in this yeast strain if you would like this project to succeed?
a. the presence of foreign double-stranded RNA
b. the presence of genes in the genome that code for RISC proteins
c. the presence of miRNA genes in the genome
d. the presence of single-stranded siRNAs within the cell
Answer:
b. the presence of genes in the genome that code for RISC proteins
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring pathway by which eukaryotic cells can silence specific genes both at the transcriptional (eg., by triggering DNA methylation on specific loci) and posttranscriptional (e.g., by triggering mRNA degradation) levels. This mechanism (RNAi) is widely used in molecular biology laboratories in order to silence genes and thus understand their functions. During the RNAi pathway, double-stranded RNAs (dsRNAs) are cleaved into small double-stranded RNA (dsRNA) molecules known as small interfering RNAs (siRNAs) or microRNAs (miRNAs) by an enzyme referred to as "Dicer". Subsequently, these small non-coding RNAs bind to an enzymatic complex known as RNA-induced silencing complex (RISC) that contains a ribonuclease enzyme, i.e., an enzyme that degrades RNA. Finally, the small non-coding RNA (either siRNAs or miRNAs) that are complementary to the RNA target directs the RISC complex to bind and cleave specific mRNAs, thereby silencing gene expression (in this case, by the inhibition of protein translation).

Cómo se denomina al tipo de acción metabólica que genera la glucólisis y respiración celular?
Answer:
catabolismo.
Explicación:
El tipo de acción metabólica que genera la glucólisis y la respiración celular se llama catabolismo porque en ambos procesos se descomponen las moléculas lo cual es una acción catabólica. El catabolismo es una forma de metabolismo que descompone moléculas más grandes en unidades más pequeñas que son utilizadas por la célula para liberar energía o utilizadas en otras reacciones anabólicas significa la síntesis de moléculas complejas en organismos a partir de otras más simples.

Why are ferns and mosses poorly adapted to a terrestrial life
Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).

Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway. You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal. You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present. When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
Answer the following question in the space give.
A. From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Answer:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
Explanation:
Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

Answer:it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation
Explanation:
The choice that best describes the image shown above is it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation. The correct option is C.
What is asexual reproduction?Asexual reproduction is a mode of reproduction in which only one parent is needed. There are different types of asexual reproduction, like budding, vegetative reproduction, fragmentation, and binary fission.
This reproduction does not require the fusion of sperm and egg. The offspring is exactly identical to the parent. Many organisms reproduce in asexual reproduction, hydra, paramecium, starfish, etc.
Thus, the correct option is C. it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation.
