the growth of plant seedlings is usually
A.phototropic and gravitropic
B.thigmotropic and gravitropic
C.phototropic and influenced by ethylene
D.gravitropic and influenced by ethylene

Answers

Answer:

The correct answer is - A. phototropic and gravitropic.

Explanation:

A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.

The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

Which of the following experimental approaches is least likely to be used in identifying transcription factor binding sites?
a. Electrophoretic-mobility shift assay
b. Northern blotting
c. DNA footprinting
d. Chromatin immunoprecipitation

Answers

Northern blotting is the least likely to be used in identifying transcription factor binding sites. Therefore, option "B" is correct. Northern blotting is used for the analysis of RNA in the given sample. The samples can be tissue, blood, and serum.

The RNA is purified from the given sample. The sample might contain fragmented RNA which is purified and amplified. The target RNA is separated by using an electric current. The RNA moved through the gel which act like a sieve-like matrix. The movement of the fragments depends on the size of the fragments. Smaller fragments move faster than larger ones in Northern blotting.

does this an suggest evolutionary relationship? explain how these embryos can be used as evidence of a common ancestor between each of these six organism​

Answers

Answer:

Examination of vertebrate embryos reveals that during corresponding stages of early development,

the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in

which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop

into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,

which persist in some animals but regress during the later stages of development of humans. Thus,  

the individual development of an animal occurs through a series of stages that paint a broad picture

of the evolutionary stages (phylogeny) of the species to which it belongs.

"Ontogeny recapitulates Phylogeny", Haeckel

Explanation:

sure po ito

Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.

For example, all vertebrate embryos by skip thru levels in which they have got gill pouches. The pouches subsequently turn into the gill equipment in fish; in later evolving vertebrates that don't have gills, the gill pouches go through similar refinement and develop into systems related to the pinnacle and neck. Similarly, all early vertebrate embryos have tails, which persist in a few animals however regress at some point in the later levels of improvement of humans.

What is ontogeny recapitulates phylogeny?

These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.

Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

1. The parent cell is dividing into two daughter cells.
2. The daughter cells are genetically identical to each other. c. The parent cell is a somatic cell. It is not a gamete because gametes are produced by meiosis, not mitosis. d. The end result of this process is two genetically identical daughter cells. e. The daughter cells are genetically identical to each other. They are the same because they are produced by mitosis, which involves only one round of cell division and results in two daughter cells that are genetically identical to each other.

Assume you saw biofilm formation on the negative control slide. What could account for such an observation? A You left the slide to incubate for too long. B The crystal violet dye was contaminated. с You used non-sterile slides or filter paper.

Answers

If biofilm formation is observed on the negative control slide, it could be due to either leaving the slide to incubate for too long (Option A) or using non-sterile slides or filter paper (Option C).

In biofilm experiments, the negative control is expected to show no biofilm formation since it does not contain the target microorganisms or conditions necessary for biofilm growth. If biofilm is observed on the negative control slide, it suggests that something went wrong during the experimental procedure. Option A suggests that the slide was left to incubate for too long, allowing unintended microbial growth and biofilm formation. Option C suggests that non-sterile slides or filter paper were used, introducing microorganisms or contaminants that can form biofilms. Both scenarios result in the presence of biofilms on the negative control slide, indicating a procedural error or contamination issue.

Answers

Answer:

186

Explanation:

The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130  bp + (14 bp x 4) = 130 + 56 = 186.

B Regions that have the same animal communities
C Small habitat such as a tree stump that contains its own ecosystem
D Large areas of the Earth that have similar climates and organisms

Answers

Small habitat such as a tree stump that contains its own ecosystem is not a characteristic of biome.

What is a biome?

A biome is a large geographic region on Earth that is characterized by a specific set of climatic and environmental conditions, as well as a distinctive community of plants and animals. Biomes are defined by their dominant vegetation, which is adapted to the specific climate and environmental factors of the region. There are several different types of biomes, including forests, grasslands, tundra, deserts, and aquatic biomes such as oceans and freshwater ecosystems. Biomes are important for maintaining biodiversity and ecological balance, and are also valuable for human use, providing resources such as timber, food, and water. The study of biomes is an important aspect of ecology, and helps us understand how living organisms interact with their environment.

Which of these is not a characteristic of a biome?

c) Small habitat such as a tree stump that contains its own ecosystem. The other options are all characteristics of a biome. Biomes are large areas of the Earth that have similar climates and organisms, and are characterized by the same plant and animal communities. Biomes are typically defined by their predominant vegetation type and are classified based on factors such as temperature, precipitation, and soil type. Therefore, option C is the correct answer.

C. the ability to grow tall

Answers

Explanation:

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.
