This passage describes the flower position trait in pea plants:Flowers can grow in different positions on a pea plant's stem. Axial flowers arein the middle of the plant's stem. Terminal flowers are at the tip of the stem.In a group of pea plants, some individuals have axial flowers and others have terminalflowers. In this group, the gene for the flower position trait has two alleles. The allele F is foraxial flowers, and the allele f is for terminal flowers.A certain pea plant from this group has axial flowers. This plant has one allele for axialflowers and one allele for terminal flowers.Based on this information, what is this pea plant's genotype for the flower position gene?axial flowersFfffterminal flowers
Axial flowers are in the middle of the plant's stem.
Terminal flowers are at the tip of the plant's stem.
The alleles that code for the trait "position of the flower" are F: axial flowers, and, f: terminal flowers.
A pea plant has axial flowers (Phenotype of the plant)
You know that it has one allele for axial flowers, F, and one allele for terminal flowers, f.
→ The genotype of the plant is then Ff (heterozygous)

The law of _____ suggests that the orbit of planets is not circular but _____. Fill in the blanks: circles triangles ellipses rectangle
Answer:
Explanation:
Kepler's First Law: The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a “flattened” circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.
The law of ellipses suggests that the orbit of planets is not circular but ellipses
Therefore your answer would be; Ellipses
Answer:
The law of ellipses suggests that the orbit of planets is not circular but elliptical.
Explanation:
Kepler's first law (the law of ellipses) explains that the orbit of the planets around the sun is not in a circular but elliptical path.
What two parts of a nucleotide create the
backbone of DNA?
Two strands that form DNA are twisted together to form a ladder-like structure. Each strand's backbone is made up of deoxyribose and phosphate units that alternate in direction.
How does DNA work and what does it look like?The instructions needed to build every protein an organism will ever need are encoded in its DNA, which is its genetic memory. The cell nucleus of eucaryotes houses DNA. An individual DNA molecule is made up of two complementary chains of nucleotides. An explanation of heredity's mechanism is provided by DNA's structure.
The nucleotides that make up DNA are chemical building blocks. One of four different types of nitrogen bases, a phosphate group, a sugar group, and these building blocks are the three components that make them up.
Genetic, immunological, and structural activities of DNA are now three separate and radically different roles.

Is the method "Reduce, Reuse, Recycle" useful in getting rid of plastic in our environment?
The method "Reduce, Reuse, Recycle"is really important for managing human impacts in our environment. The less plastic we consume (reducing), the better. As much as we can reuse the plastic, the better also. We wouldn't be creating that many trash and would be reducing pollution. Recycling is always the best way to deal with our trash, so it won't be harmful to the environment. However, to really get rid of plastic in our environment it is important to stop producing plastic as well, not only reducing the consume, reusing the plastic and recycling the trash

the chloroplasts of land plants are thought to have been derived according to which evolutionary sequence?
the chloroplasts of land plants are thought to have been derived according to evolutionary sequence:
cyanobacteria → green algae → land plants
A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.
This concept has had a fresh influence on the notion of Darwinian evolution and has been discovered to apply to the whole sequence. It is well demonstrated in the orderly copolymerization of amino acids. I'll go through a few issues with handling the teaching of contentious themes in this section.

What type of growth graph is shown below for a woodpecker population?text Question 10 options:exponential growthlogistic growthlinear growth
When we are talking of population growth we must take into consideration more factors than just growth rate. In the case of exponential growth, we have that the growth rate per capita, that is to say per individual, is constant regardless of the population size, so it grows as the population grows. Meanwhile, in logistic growth, the growth rate per capita creases as the population size approaches a maximum imposed by the limiting resources, that is to say, the carrying capacity of an ecosystem. Therefore we can say that the correct answer is logistic growth.

Does lymph can direct through the arteries
Lymph, which is a substance different from the blood that carries out nutrients from the extracellular media of the different tissues of our body, flows through specific vessels, known as lymphatic vessels, so they don't go directly through the arteries, as we can see in the following picture:
scientists in the 1950s performed an investigation to test whether organic compounds could beproduced by stimulating the conditions of primitive earth. They placed a simple compoundsthey thought existed in the atmosphere of early earth in a heated vessel and used electricsparks to stimulate lightning. Then they determined whether sugars and amino acids werepresent period which of the following would not be an appropriate scientific activity?A. Using the results to design an additional investigation.B. making a prediction before beginning the investigation.C. systematically recording the results of the investigation.D. choosing data that confirmed the hypothesis of the investigation.
to answer the question, we will discuss each item:
A) The results obtained during an investigation are information that can be used to design subsequent experiments that will answer questions that could not be answered in the first experiment.
B) The activity of making a prediction before performing an experiment is called hypothesis, which is based on observations. That is, first we will observe the phenomenon, and based on our reasoning we will generate a prediction or hypothesis that we will test with an experiment to see if it is correct.
C) An important part of the research is to have detailed records of each part of the experiment, this way if there is an error we can know in which part of the experiment it occurred and also we can give this information to other researchers so that they can replicate the experiment and confirm the results we obtained.
D) Finally, when the experiment is finished and when we are analyzing the information, we must take all the data into account and not only those that confirm our hypothesis, since that would give us an erroneous conclusion and would be a bias of information. Therefore, the answer is D.
Which type of mutation speaks produces a stop condon?
Answer:
nonsense mutation
Explanation:
You go on a canoe trip to the Boundary Waters Canoe Area (BWCA) in Northern Minnesota. Thisecosystem is cold most of the year and receives plenty of rainfall. It has many lakes that are full ofwalleye pike fish. You know that walleye like to eat minnows. In turn the minnows feed on scuds(zooplankton) which eat algae (phytoplankton). Walleye pike fish are what?A. secondary consumersB. tertiary consumersC. primary consumersD. producersE. decomposers
In this case, we are talking of food chain, so phytoplankton is a photosynthetic organism, an autotroph, therefore is a producer, now the zooplankton is the primary consumer, which makes the minnows a secondary consumer and in turn, the Walleye pike fish is a tertiary consumer. Taking this into account we can say that the correct answer is option B.
Based on what we learned so far from the article, what can you say about the peas we eat or purchase?
Based on the article, the color, length, and taste of peas that we eat or purchase is based on hormones and enzymes that affect the peas' development. If there is a presence of mutation, an enzyme will not be produce making the pea remain as green instead of yellow. Mutation is also the reason behind the taste of peas that are extra sweet because of the different enzyme produced. The length of peas is also based on an enzyme production. If such enzyme is not present, there is a mutation making the peas short.

E) All of these pairs are correct.
The pairs of base sequences could form a short stretch of a normal double helix of DNA is:
D) 5'-ATGC-3' with 5'-GCAT-3'
In DNA, the code letters are A, T, G, and C, which stand for the chemical substances adenine, thymine, guanine, and cytosine, respectively. Under normal occasions, the nitrogen-containing bases adenine (A) and thymine (T) pair collectively, and cytosine (C) and guanine (G) pair collectively. The binding of those base pairs forms the structure of DNA.
Because of the base pairing, the DNA strands are complementary to each different, run in opposite guidelines, and are referred to as antiparallel strands.
Complementary base pairing is important in DNA because it lets the base pairs be arranged in the maximum energetically favorable way; it's miles crucial in forming the helical structure of DNA. it's also critical in replication as it allows semiconservative replication.
You could determine the sequence of a complementary strand if you are given the series of the template strand. These strands are complementary, with each base in one sticking to its partner on the alternative. The A-T pairs are linked by means of two hydrogen bonds, whilst the G-C pairs are connected through three hydrogen bonds.
