The dandelion is a successful weed. Explain why its adaptations make it a better competitor than many other plants on a school field or a garden lawn.
Answer:
The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.
Explanation:
The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.
Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind. Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.

If 70% of the alleles in a gene pool of a population are dominant, the frequency of the
Answer:
Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to
If DNA read A-T-T-A-C-G-G-C-C what would the RNA read? Why is DNA replication important?
If DNA read A-T-T-A-C-G-G-C-C the RNA would be U-A-A-U-G-C-C-G-G
DNA replication is important because new cells require their own strand of the DNA. Without replication, there would be no new organisms because the DNA’s information would not be passed on.
Given that the diploid number of cattle is 60 (2n = 60) how many pairs of chromosomes do cattle have?
Answer: 30
Explanation:
Diploid is simply referred to as a cell or an organism which possess paired chromosomes. The paired chromosomes are gotten from each of the parents.
It should be noted that the total chromosomes that will be found in the cattle's somatic cell is 60. Therefore, the pair will be 60/2 = 30.

Rose conducted an experiment to study the effect of temperature change on the heart rate of Daphnia, transparent aquatic invertebrates commonly known as water fleas. She heated three different beakers of water containing Daphnia to a different temperature: 30°C, 32°C, and 34°C. She put a drop of water from each beaker on a slide mount and used a microscope to observe Daphnia in each sample. She counted the number of heartbeats in one minute and averaged her results. Which of the following could be a step in a replication of this experiment?
Answer:
Rose's classmate Mina observing Daphnia in water at 30°C, 32°C, and 34°C.
A step in replication of Rose's experiment could be to repeat the procedure of heating three different beakers of water containing Daphnia to 30°C, 32°C, and 34°C, counting the number of heartbeats in one minute for each sample using a microscope and slide mount, and averaging the results.
What is Daphnia?Daphnia, also known as water fleas, are small, transparent aquatic invertebrates that are commonly used in scientific experiments to study the effects of environmental factors on living organisms. In many experiments, Daphnia are subjected to changes in temperature, light, oxygen levels, and other variables to determine how these changes impact their behavior and physiology.
One example is studying the effect of temperature on heart rate, as done by Rose in the experiment described above. The use of Daphnia in experiments is beneficial because they are easy to culture, reproduce quickly, and are small and simple enough to be easily manipulated in the laboratory. Additionally, because Daphnia are freshwater organisms, they are particularly sensitive to changes in their environment, making them useful for investigating the impacts of various stressors on aquatic ecosystems.

which steps of the greenhouse effect are most affected by the increases in greenhouse gases, leading to increase in heat?
Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

Explanation:
[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]
_____________________________________[tex]\Large\textbf{Phenotype:}[/tex]
It is the physical appearance of the trait, whether the plant has Long stem or short stem.
[tex]\Large\textbf{Genotype:}[/tex]
A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.
_____________________________________Alleles:Allele Long stem A is dominant over short stem a
Genotype of Parent Pea PlantsPea Plant 1 has genotype Aa
Pea Plant 2 has genotype aa
_____________________________________[tex]\Huge\text{Question:}[/tex]The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.
Heterozygous PlantsHeterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3
_____________________________________Best Regards'Borz'What events cause exhalation?
Answer:
The process of exhalation occurs due to an elastic recoil of the lung tissue which causes a decrease in volume, resulting in increased pressure in comparison to the atmosphere; thus, air rushes out of the airway. There is no contraction of muscles during exhalation; it is considered a passive process.

b. Serine-Arginine-Cysteine-Stop
c. Arginine-Leucine-Isoleucine-Alanine-Threonine
d. Alanine-Valine-Cysteine-Arginie-Threonine
Answer:
a. Serine-Alanine-Isoleucine-Isoleucine-Glycine
Explanation:
This question is describing gene expression, which comprises of transcription and translation. Transcription is the process by which a DNA molecule is used as a template to synthesize a mRNA molecule while in translation, the mRNA is used to synthesize an amino acid sequence using a set of three nucleotide bases called CODON in the mRNA.
According to this question, the following DNA sequence is given: AGTCGCTATTAGCCG. The process of transcription will form the following mRNA sequence from this DNA sequence: UCAGCGAUAAUCGGC.
Translation will make use of the genetic code to produce the following amino acids. Note that, one codon e.g UCA encodes an amino acid (serine).
The amino acid sequence is: Serine-Alanine-Isoleucine-Isoleucine-Glycine.
UCA codes for Serine
GCG codes for Alanine
AUA codes for Isoleucine
AUC codes for Isoleucine
GGC codes for Glycine
