The population of white pines on his land in 2015 was 40. After last weekend the population is 155. Find the growth rate.
Answers
Answer:
287.5%
Explanation:
Initial = 40
Recent = 155
Growth rate = ( recent - initial )÷ initial ×100/1
=( 155-40/40) × 100/1
= 115/40×100/1
= 2.875×100/1
= 287.5%

Which fallacy does the following statement or argument commit:i. All politicians are snakes. ii. No snake has legs. iii. So, no politician has legs. (a) begging the question(b) false dichotomy(c) equivocation(d) fallacy of division(e) fallacy of composition
Answers
The fallacy committed by the given statement is the fallacy of composition. This fallacy occurs when someone assumes that what is true for one part of a group must be true for the whole group.
In this case, the argument assumes that since no snake has legs, therefore no politician has legs. However, this assumption is incorrect as politicians are not the same as snakes, and
their physical characteristics cannot be assumed based on the characteristics of a completely different species. Therefore, the argument is flawed as it incorrectly assumes that a characteristic of a part of a group applies to the whole group. This is the fallacy of composition.

3. In the diagram of a cell below, the structure
labeled X enables the cell to
2
(1) release energy
(3) control cell activities
(2) store waste products (4) manufacture proteins
4 If the ribosomes of a cell were destroved whatsoever
Answers
If the ribosomes in the cell were destroyed the cell would not be able to grow (growth and repair)
Answer:
Explanation:
In the diagram you provided, the structure labeled X is the endoplasmic reticulum (ER). The endoplasmic reticulum is a network of flattened sacs and tubes that is found within the cytoplasm of eukaryotic cells (cells that have a nucleus and membrane-bound organelles).
There are two main types of endoplasmic reticulum: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER). The rough endoplasmic reticulum is studded with ribosomes, which are small organelles that synthesize proteins. The smooth endoplasmic reticulum, on the other hand, does not have ribosomes attached to it.
The endoplasmic reticulum plays several important roles in the cell, including:
1. Release of energy: The endoplasmic reticulum is involved in the synthesis of lipids and the breakdown of carbohydrates, which releases energy that can be used by the cell.
2. Control of cell activities: The endoplasmic reticulum helps to regulate the synthesis and transport of proteins and lipids within the cell.
3. Storage of waste products: The smooth endoplasmic reticulum is involved in the synthesis and detoxification of certain substances, such as drugs and hormones.
4. Manufacture of proteins: As mentioned, the rough endoplasmic reticulum is involved in the synthesis of proteins. Proteins are synthesized on the ribosomes attached to the RER and are then transported into the lumen (cavity) of the RER for further processing and modification.
If the ribosomes of a cell were destroyed, the cell would no longer be able to synthesize proteins, which would severely impact its function and survival.

Answers
Answer:
The best way to test the effectiveness of a vaccine against a disease is vaccinate 50 animals, do not vaccinate 50 other animals, and expose all 100 to the disease (option C).
Explanation:
When testing a vaccine for effectiveness, the option is to administer the vaccine to half of the population exposed to a disease, since effectiveness should measure the performance of the vaccine within a community.
If there are 100 animals exposed to a disease, the fact that the 50 vaccinated animals do not get sick is an excellent test of how the vaccine works and what its effectiveness is.
The other 50 animals, not vaccinated, would act as a control group exposed to the same disease and sharing a certain space.
The other options are not correct because:
A. Vaccinating the 100 exposed animals does not provide an unvaccinated control group to compare the effects of the vaccine.
B. Vaccinating all 100 animals and exposing only 50 to the disease does not make sense, since it would not be possible to measure effectiveness in vaccinated animals that are not exposed.
D. Vaccinating 50 animals and not vaccinating the other 50 to expose only the vaccinated animals to the disease does not make sense since the conditions of the test group and the control group should be the same.

Answers
The sympathetic division of the autonomic nervous system stimulates and speeds up certain bodily activities.
The sympathetic division of the autonomic nervous system, often referred to as the "fight or flight" response, activates and speeds up various bodily activities in response to stress or perceived threats. When stimulated, the sympathetic division triggers a cascade of physiological changes.
These include increased heart rate and blood pressure to prepare for physical exertion, dilation of the airways to enhance oxygen intake, and release of adrenaline and noradrenaline to boost energy levels. It also inhibits non-essential functions such as digestion, in order to redirect resources towards immediate survival-oriented actions. Overall, the sympathetic division readies the body for action, promoting heightened alertness and increased physical performance.

Inferior vena cava returns deoxygenated blood to the right side of the heart from all parts Abdominal organs, Pelvis and Lower extremities.
The inferior vena cava is the largest vein in the human body that connects the lower body to the right atrium of the heart. It brings deoxygenated blood from all parts of the body back to the right side of the heart. This includes the abdominal, pelvic, and chest cavities, along with the lower extremities, such as the legs and feet.
This blood is then reoxygenated and sent back to the left side of the heart from where it goes back to the lungs in order to get reoxygenated again. In order to traverse the various cavities, the inferior vena cava has to navigate a number of major valves. The most common ones being the iliac vein valves, which keep the blood flowing in the required direction.

considering biological causes of gender differences more immutable than social ones is a mistake because
Answers
Considering biological causes of gender differences more immutable than social ones is a mistake because biological differences do not completely determine gender roles or behavior.
Gender identity, expression, and behavior are also shaped by social, cultural, and environmental factors.
Biological differences, such as sex chromosomes, hormones, and reproductive organs, do play a role in gender development. However, these differences do not dictate gender roles or behavior. For example, while testosterone levels may influence aggression, not all males exhibit aggressive behavior, and not all females lack aggression.
Instead, gender is a complex interplay of biological, social, cultural, and environmental factors. Socialization and cultural expectations are particularly influential in shaping gender roles and behavior. Children learn gender norms and expectations from their families, peers, media, and other social institutions from an early age. These social factors can have a significant impact on the development of gender identity and expression. Biological and social factors interact to shape gender differences and variation. Focusing exclusively on biological differences as the primary cause of gender differences ignores the complexity and variability of gender and reinforces limiting gender stereotypes.

within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers?
Answers
Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
----------------------------
There are different mechanisms involved in producing genetic variation among descendants. These are,
Crossing-over between homologous chromosomes (prophase 1), Random lining of homologous chromosomes (metaphase 1),Random fertilizationThe Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
In the attached imaged there are four different stages of meiosis.
Stage C is the one that contributes the most to diversity.
We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.
In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

what group of vertebrates has: a head, jaws, lungs, lobe fins, legs but no amniotic egg?
Answers
The group of vertebrates that have a head, jaws, lungs, lobe fins, legs but no amniotic egg is the class Amphibia.
An amniotic egg is an egg that has a specialized membrane that protects the developing embryo and allows the egg to be laid on land without drying out. The lack of an amniotic egg is a defining characteristic of amphibians.
Amphibians belong to the class Amphibia. The other groups of vertebrates are fish (including jawless fish, cartilaginous fish, and bony fish), reptiles (including turtles, lizards, snakes, crocodiles, and birds), and mammals (including monotremes, marsupials, and placental mammals).
Amphibians are cold-blooded, vertebrate animals that live both on land and in water. Their skin is thin, moist, and permeable, which allows them to absorb oxygen and moisture directly from their surroundings. They have legs (or sometimes no legs), and lungs (or sometimes gills), and are able to reproduce sexually. Some common examples of amphibians include frogs, toads, salamanders, and newts.

Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
1. sister chromatids / centromeres:
2. mother cell / daughter cell: Identical
3. interphase/ cell division:
4. DNA / chromosome:
5. mitosis / cytokinesis:
Answers
Answer:
Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.
A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.
Mother cell / daughter cell: identical.
Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.
On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.
Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,
replicates its chromosomes, and prepare for cell division.
The cell then leaves Interphase, undergoes mitosis, and completes its division.
DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body
Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.
Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
