Dicots - beans, peaches, and potatoes
Flowering plants are classified into two major groups based on the number of cotyledons (seed leaves) present in the embryo. The two groups are; Monocots (Liliopsida) and the Dicots (Magnoliopsida). Monocots possess only one thin seed leaf inside the seed coat, while dicots possess two rounded and large seed leaves inside the seed coat. Monocots have a fleshy and unbranched stems, while dicots have a branched and very tough or woody stem. Also, the leaves of monocots are usually narrow and long with parallel veins, while the leaves of dicots have various sizes and shapes with netted pattern.

In josh, who is undergoing puberty, ________ is (are) a primary sexual characteristic; and ________ is (are) a secondary sexual characteristic
In Josh, who is undergoing puberty, the development of the male reproductive part is a primary sexual characteristic and voice changes are secondary sexual characteristics.
What are Sexual Characteristics?Sexual characteristics are defined as the physical characteristics of an organism that indicate its biological sex which may include sex organs used for reproduction and secondary sexual characteristics that differentiate the sexes of a species , but which are not directly part of the reproductive system.
Adolescent changes relate to both primary and secondary characteristics, where primary are present at birth, including external and internal genitalia while secondary are present at birth that emerge through the later stages of puberty (eg, breasts in females and pigmented facial hair in males).
Thus, in Josh, who is undergoing puberty, the development of the male reproductive part is a primary sexual characteristic and voice changes are secondary sexual characteristics.

Flushing is a common side effect from taking high levels of which nutrient? umuc
The answer is Vitamin B3 (also called Niacin). To reduce flushing, it is recommended to take it in increasing doses. Its uptake in large quantities reduces cholesterol levels of the body and therefore, reduces the levels of cardiovascular diseases. However, these large quantities could also cause gastro intestinal complications, liver damage and glucose intolerance.
Flushing is a common side effect of taking high levels of Niacin (Vitamin B3). This happens due to the dilation of small blood vessels which increases blood flow to the skin surface. It's generally harmless but can be uncomfortable.
Explanation:Flushing, or a warm sensation and redness on the skin, is a common side effect of taking high levels of Niacin, also known as Vitamin B3. This phenomenon occurs due mostly to the dilation of small blood vessels, causing increased blood flow towards the surface of the skin. This is particularly visible on the face and upper body. It is generally harmless but can be uncomfortable. If you are taking high levels of niacin and experiencing flushing, it is recommended that you consult with a qualified health professional.

If this trisomic male (ey+ ey-, gw+ gw-) is crossed with a (ey− ey−, gw− gw−) female, what proportion of the progeny will be phenotypically wild-type?
In an X-linked cross between a white-eyed male and a heterozygous red-eyed female fruit fly, 50% of the offspring would be phenotypically wild-type, exhibiting red eyes, while the other 50% would be phenotypically non-wild-type, exhibiting white eyes.
Explanation:In an X-linked cross between a white-eyed male fruit fly (ey-) and a female fruit fly that is heterozygous for red eye color (ey-), the offspring would exhibit a 1:1 ratio of phenotypically wild-type to non-wild-type individuals.
Specifically, 50% of the offspring would be phenotypically wild-type, meaning they would have red eyes. These individuals would inherit the wild-type allele (ey+) from the female parent and the wild-type or non-wild-type allele (ey+ or ey-) from the male parent.
The other 50% of the offspring would be phenotypically non-wild-type, meaning they would have white eyes. These individuals would inherit the non-wild-type allele (ey-) from both parents.

Habitat destruction is the leading cause for declining populations of species on our planet. Due to human development, industry, and forestry, humans are destroying the habitat of many species at an alarming rate. Consider the bald eagle. The bald eagle population was threatened in the late 60s and early 70s. Thanks to an aggressive bald eagle protection program, bald eagle numbers in the wild have soared as seen in the population graph above. The bald eagle's population very nearly reached extinction. Why did the bald eagle's declining population make it more vulnerable to extinction?
Answer: Due to loss of genetic diversity.
Explanation:
Genetic diversity is the variation in the genes among the population of organisms.Genetic diversity helps the organisms to adapt to the changing environments and hence, increase their population.As the population of the endangered species is reduced, their genetic diversity is also lost.So, due to the loss of the genetic diversity the bald eagle's declining population becomes more vulnerable to extinction as they cannot adapt to the changing environment.Which type of irrigation loses the most water to evaporation?

Select all that apply. Which of the following are not properties of enzymes? a.)not required to sustain the life of an organism b.)sensitive to pH and temperature of their environment c.) able to interact with all compounds or substrates d.)large proteins with a special surface pattern
Enzymes are crucial for life, sensitive to pH and temperature fluctuations, and are large proteins with a unique structure that fit their specific substrates. They do not, however, interact with all compounds or substrates, showing specificity for their particular substrates.
Explanation:Enzymes, as biological catalysts, are crucial for life and possess specific properties. Let's address your multiple-choice question concerning properties that enzymes do NOT have:
a) Not required to sustain the life of an organism - Incorrect, enzymes are necessary for life as they accelerate chemical reactions in the body by decreasing the activation energy. Without enzymes, these reactions wouldn't occur quickly enough to sustain life. b) Sensitive to pH and temperature of their environment - Incorrect, this is a genuine characteristic of enzymes. Enzymes work optimally within specific temperature and pH ranges; outside these ranges, enzymes may become denatured and lose their functionality. c) Able to interact with all compounds or substrates - Correct, enzymes do NOT interact with all compounds. They demonstrate specificity, meaning each enzyme has an active site that uniquely fits with its specific substrate(s). d) Large proteins with a special surface pattern - Incorrect, enzymes are indeed large proteins with a unique surface structure, allowing them match with their substrates.
In summary, the property that is NOT true of enzymes is that they are able to interact with all compounds or substrates.

a) Not required to sustain the life of an organism.
c) Able to interact with all compounds or substrates.
Enzymes are essential for sustaining life as they catalyze biochemical reactions crucial for various physiological processes. Enzymes are highly specific and interact only with particular substrates due to their unique active sites. They do not interact with all compounds.
Enzymes are indeed sensitive to pH and temperature because extreme conditions can alter their structure and function. They are also large proteins with a special surface pattern, which facilitates their specific interactions with substrates. The specificity and sensitivity of enzymes are key factors in their role in biological systems.

The classification of organisms that is based exclusively on the evidence of evolutionary relationships is called ____________. traditional classification cladistic classification biological classification morphological classification systematic classification
Cladistic classification is the method used to classify organisms based on evolutionary relationships. It involves the construction of phylogenetic trees using various forms of data, and is a part of the field of systematics. Cladistics is an important method in this process.
Explanation:The classification of organisms based on the evidence of evolutionary relationships is known as cladistic classification. This method involves mapping out the relationships between different species or groups of organisms based on their evolutionary history. Scientists accomplish this by building phylogenetic trees - which are essentially hypotheses of how different forms of life might have evolved and diverged from common ancestors. This complex task requires the careful consideration of various data such as morphological, genetic, and molecular evidence.
To put this into process, scientists use systematics - a field devoted to organising and classifying organisms based on these evolutionary relationships. The combined data from different sources allows experts to put together the phylogeny of an organism, and thus present a probable picture of life's diverse evolutionary journey. An important methodology within this process is cladistics, which distinguishes between homologous (shared) and derived (unique) characteristics to better understand the relationships between groups.
