Answer:Toothed whales do not make the long, low-frequency sounds known as the whale song. Instead they produce rapid bursts of high-frequency clicks and whistles. Single clicks are generally used for echolocation whereas collections of clicks and whistles are used for communication.
Read about invasive species. Then answer the questions provided. Wild Parsnip Describe the invasion of wild parsnip, including the harm it causes.
Answer: An invasive species is the one which compete for resources with the native species.
Explanation:
Wild Parsnip is an invasive species of plant in Europe and Asia. It grows on the roadside and the seeds of the plant disperse very easily by wind and water agents. It spreads easily and compete with native species for resources like soil nutrients, water, and others. It produces a chemical that causes rash in the human skin and the human skin becomes sensitive to sunlight resulting in development of blisters and rashes on the skin.
Answer:
came from Europe and Asia
invaded the entire state of Wisconsin

Answer:
Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.
Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.
Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

Complete the complementary strand of DNA, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Mark the 5' and 3' direction of the strands,
Drag the appropriate labels to their respective targets. Terms can be used once, more than once, or not at all
About the question:
You will find the completed strand in the attached files
Answer and Explanation:
First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,
The original strand is the one at the left,The complementary strand is the one at the right.Now we need to recognize and pair the bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Once we drag the base labels to their targets, we need to recognize each of the strain extremes.
One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.
So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.

With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.
Answer:
be beneficial.
Explanation:
Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.

Produces and secretes bile. Alternates contraction and relaxation of smooth muscles along the length of the GI tract. Largest salivary gland anterior to each ear. Another term for chewing. Covers dentin and glues the teeth to the periodontal ligament. Secrete hydrochloric acid in the stomach. Vessels absorbing and transporting fatty acids and monoglycerides. Pancreatic juice enters this region of the small intestine. Has both endocrine and exocrine functions. Finger-like extensions in the epithelial cell membrane.
Answer:
The correct answer would be -
1. liver 2. peristasis 3. parotid 4. mastication 5. cemuntum 6. parietal cell 7. Lacteal 8. duodenum 9. Pancreas 10. microvilli
Explanation:
The liver is the gland or the organ that is responsible for the production of bile and secreted into the duodenum during digestion.
Peristalsis is the movement that helps in forwarding propulsion of food/bolus
The parotid is a gland that produces and secrets saliva for moistening the food and digesting carbohydrates.
Mastication is a process that helps in crushing and breaking the food into smaller pieces.
Cementum is a substance that covers the root of the teeth and glues the teeth to the periodontal ligament.
Parietal cells secrete hydrochloric acid to remove the pathogens and activating pepsinogen.
Lacteal vessels absorb fatty acids and transport them
Duodenum is the region where pancreatic juice and bile is secreted.
The pancreas is an organ and gland that acts as exocrine and endocrine gland
Microvilli are the projection look like fingers in the epithelial cell membrane.
(c) Based on the data, describe the time period during which Chlorella approximates exponential growth. Based on
the data and assuming logistic growth, describe the time period during which the Chlorella population has reached
the carrying capacity of the culture. Based the data, calculate the growth rate per day for the 5-day period with
the greatest growth rate.
Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day
What is the logistic growth model?In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Assuming that the population size is N, when
N<K, the population can still grow. N approximates to K, the population's growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
In the example,
Between 0 and 5 days the population remains relatively stableBetween 5 and 10 days Chlorella approximates exponential growth.Between 10 and 20 days Chlorella experiences exponential growth. Between 20 and 25 days the population is near the K and decreases its growth rate.From 25 to 30 days, the population reached the equilibrium point, and got to stabilize.Time period during which Chlorella,
A) approximates exponential growth ⇒ Between 5 and 10 days
Between 10 and 20 days its already exponential growth.
B) has reached the carrying capacity of the culture ⇒ 25 to 30 days
Finally,
C) Growth rate per day for the 5-day period with the greatest growth rate.
First we need to figure out during which period Chlorella experiences the greatest growth rate. To do it, we just need to make the following substraction,
Growth rate per period = final concentration - initial concentration
Period 0-5 ⇒ 0.08 - 0.01 = 0.07Period 5-10 ⇒ 0.55 - 0.08 = 0.47Period 10-15 ⇒ 1.9 - 0.55 = 1.35Period 15-20 ⇒ 2.8 - 1.9 = 0.9Period 20-25 ⇒ 3.2 - 2.8 = 0.4Period 25-30 ⇒ 3.2 - 3.2 = 0Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,
1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day
The answer is 0.27 x 10⁶ cells/mL/day

Compare the concentration of connective tissue cells found in bone with the concentration of those found in blood.
Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).
Explanation:
Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:
--> Loose connective tissue
--> Dense connective tissue and
--> specialised connective tissue.
The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.
The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.
The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.
In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.

Why do hydrogen atoms form a molecule but helium atoms do not?
Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
Hydrogen atoms can form a molecule as 2 hydrogen atoms together can result in a low energy combination of 2 electrons of the same energy level.
Explanation: Helium atoms already have 2 electrons of the same energy so therefore it cannot accept more.
