Answer: Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. Territorial boundaries may be marked by sounds such as bird song, or scents such as pheromones secreted by the skin glands of many mammals.
Explanation:
Answer:
Wolves work together to chase or kill any wolves that are not in
their group
Explanation:
Many animals rely on smells to mark their territories, spraying urine, leaving droppings or, rubbing scent glands around the territories' borders. Approaching animals will be warned off the territory without ever encountering the territory's defender.

Which of these is a result of crossing over?
a.) Decrease in the number of chromosomes
b.) Exchange of proteins
c.) Exchange of genetic material
d.) Increase in the number of chromosomes
The result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.
What is the importance of crossing over?"Crossing over" is a process that occurs during meiosis of cell division in sexually reproducing organisms that produces gametes such as sperm and eggs. During crossing over, the genetic material in the parent cells' chromosomes is exchanged, resulting in new combinations of genes in the gametes, and the importance of crossing over is that it creates genetic diversity within a population.
Hence, the result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.

placed on a steamy soup
D. Why chilly air always remains near the floor
2. Which of the following is NOT true about heat?
A. It is a form of energy
B. It transfers from one object to another.
C. It is caused by a temperature difference between
two objects
D. It determines the hotness or coldness of an object

Answer:
1. C. Why a handle of a metal spoon also gets hot when placed on a steamy soup.
2. D. It determines the hotness or coldness of an object.
3. D. Energy transferred due to temperature differences.
4. C. The object is a thermal insulator.
Explanation:
Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.
Down syndrome in humans is due to ________ of the 21 st chromosome.
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity

Type the correct answer in the box.
The temperature equivalent to 77°F is
°C.
Use the formula to convert the temperature.
Answer:
25 degree celcius
Explanation:
formula
(given degree Fahrenheit - 32)×5÷9
(77 - 32)× 5÷9
= 25°C
Here I will show you how to convert 77 F to C so you know how hot or cold 77 degrees Fahrenheit is in Celsius. The F to C formula is (F − 32) × 5/9 = C. When we enter 77 for F in the formula, we get (77 − 32) × 5/9 = C.
so therefore the answer is 25 degrees celsius
What happens to species diversity WITHOUT Pisaster? *
Answer:
The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities. A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

Sheila, 32 years old, has been referred to a registered dietitian following her 6-week postpartum check-up following her third pregnancy, as she has concerns about her goals of weight loss and still being able to meet her daughter’s nutritional needs through breastfeeding. This pregnancy was complicated by gestational diabetes, as was her second pregnancy. She gained 37 lbs and states she understands the need to lose her pregnancy weight to reduce the risk of developing type 2 diabetes; she wasn't successful with losing the weight from her second pregnancy. Her daughter was 9 pounds 11 ounces at birth and has been gaining weight appropriately. Sheila breastfed her first two children until they were approximately 5 months old. Her current weight is 223 lbs and her height is 5'5". She reports she hasn't started exercising yet, but she was medically cleared to do so by her physician. Sheila's 24-hour recall shows an estimated calorie intake of 2700 kcal with limited fruits and vegetables, one cup of milk, and portions of high-fat and sugary foods. She has been maintaining her weight with her current calorie intake.

Which of these islands would likely have the most species diversity.
A small island in the middle of the ocean
O A large island near the mainland
Answer:
A large island near the mainland
Explanation:
A large island has a greater number of species, a greater interaction between them and a greater number of natural elements. All of this is capable of promoting biological specialization on a large scale, allowing new species to emerge more quickly than on a small island. Although a small island may also have great biodiversity, that island has fewer factors that promote the creation of new species, in addition to having fewer species interacting and creating new species.

Explain how competition for food can cause natural selection.
Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

Explanation:
Lakesha was culturing bacteria. She used aseptic technique to make sure there was no contamination. When she was finished, she used water to clean the surface of her table. She then put the sample in the incubator, removed her gloves, and washed her hands with soap and water.
Answer:
d. She should be using a disinfectant on her table, not just water.
Explanation:
When Lakesha finished culturing the bacteria, she should not have used water alone to clean the table because water can't kill bacteria. She has to use a disinfectant in order to remove bacteria from the table. This disinfectant has the ability to kill all the bacteria that is present at the table and there is no chance of infection from these bacteria. So we can say that she made a mistake to clean the table with just water and not using the disinfectant over it.
