identify two other physical factors and explain their effect on the organism living in the lake?
Answer:
The correct answer is - light level and temperature.
Explanation:
The structure and function of lakes are determined by various factors such as temperature, light level, wind turbulence, water flow rate, dissolved oxygen, acidity (pH), salinity, habitat size, hydrology, and water depth. Stratification and water circulations are influenced by temperature and wind turbulence.
Light level is an important abiotic factor in lake ecosystems. Light is an essential part for plants to perform photosynthesis. Light can directly affect how much life you find in a given area depends on the production of energy and food by the aquatic plants by photosynthesis.
Temperature is a similarly important factor for lakes or other aquatic organisms as it is for land animals. each organism is able to survive in specific temperature ranges and their metabolic activity also depends on the specific temperature range.

A dominant gene that codes for white hair is represented by the symbol W. If a parent with the genotype WW is crossed with a parent of genotype Ww, what percent of their offspring will have white hair?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
D
Explanation:
Seeing as the gene is dominate, the hair would still be white evening it's Ww. For the hair to be a different color both parent would need a recessive gene (w), though neither does, meaning all the kids would have white hair.
What phenotypes could result from the mitotic crossing over in an individual that is heterozygous for the recessive loci of singed bristles (sn), yellow cuticle (y), and bent bristles (b) given the loci are arranged as follows:
Answer: Hello your question has some missing data attached below is the missing data
answer : single spots for “b”, “sn”, and “y” ( option C )
Explanation:
During the mitotic crossing over in a heterozygous individual the phenotypes that could result are single spots for “b”, “sn”, and “y” . this is because In mitosis/mitotic crossing there is no pairing up and no swapping of chromosomal segments Hence no variations are introduced during mitosis /mitotic crossing

Explanation:
One of the big challenges for a nucleic acid vaccine is actually getting the DNA or RNA to go inside the host cell's membrane. One way to do this is to wrap the nucleic acid up in a little package of macromolecules just like how the golgi body packages things up things we want to export. Based on this description, you would guess that the best thing to package the genetic material would be:
Question Completion:
- a large carbohydrate with partial charges
- a phospholipid
- a nucleic acid carrying
- a negative charge
- a highly polar protein
Answer:
Based on this description, you would guess that the best thing to package the genetic material would be:
- a phospholipid
Explanation:
Since phospholipids work to provide pathways for various substances across cell membranes, they appear to be the best agents or packages for exporting the genetic material of a nucleic acid vaccine. As cell membranes, phospholipids can allow selective passage of some substances into and out of the cells, even though they act as barriers to other molecules and ions.

Most of the energy radiated by Earth's surface at night is in the form of
Answer:
infrared rays
Explanation:
The energy that Earth receives from sunlight is balanced by an equal amount of energy radiating into space. The energy escapes in the form of thermal infrared radiation: like the energy you feel radiating from a heat lamp.

What type of plants commonly grows in the lower biomes of a mountain? (1 Punto)
Answer:
Alpines, Mosses, Lichens etc
Explanation:
These type of plants survive in very harsh conditions in which the mountain regions are associated with.
The conditions include a higher degree of temperature, little or no amount of soil particles, dryness and a very low degree of nutrients available to them which makes their growth usually stunted when compared to plants in other regions.
An S-shaped pattern formed when a stream flows through channels is called
Answer:
meander
Explanation:
A meander is a series of regular sinuous curves in the channel of a stream/river/watercourse, thereby forming a rounded or "S"-shaped bend curve. Meanders are common in alluvial areas that have low gradients, where they are formed by the dynamics of the watercourse. The meander belt is the zone within which a meandering watercourse occupies on its floodplain. The sinuosity is a measure to calculate the degree of meandering in the channel of a watercourse.

Which of the following is an example of homeostasis?
Q. During a time of high stress, Justin's heart races, his muscles tense, and he feels
sweat dripping down his forehead.
R. Sick with the flu, Alison's body temperature rises to fever levels.
S. Boris doesn't drink very much water one day. To compensate his kidneys remove less
fluid from his blood, and produce less urine than normal.
T. As Grace races up the ten flights of stairs to her apartment, the muscle cells in her
legs produce excess lactic acid, causing a burning sensation in her legs.

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event
based upon what is observed. A hypothesis has not been proved but can be supported by
experimentation.
a) Suppose that out of 10 trees planted in a yard, only five survived. What kind of hypothesis
you make about this observation or event? Remember that a hypothesis needs to have a certain
format.
Answer:
the yard did not have enough nutrients to support all 10 trees that were planted
Explanation:
define the process of photosynthesis
Answer:
The process by which the green plants prepare their food in presence of sunlight , water and carbon dioxide is called photosynthesis.
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Compare and contrast the methods used by bacteria and protozoa to stay alive. Even when conditions within the environment are
unfavorable for the growth and survival of the organism.
Answer:
Protozoa formed cysts and bacteria produces endospores.
Explanation:
Protozoa can survive in dry and unfavourable environments, by producing resting cysts that enable them to remain dormant until conditions are favourable while on the other hand, bacteria produce special dehydrated cells called Endospore which helps the bacteria to survive unfavourable environmental conditions. These endospores help bacteria to resist high temperature, radiation, drying, and other environmental extremes.
Why are ferns and mosses poorly adapted to a terrestrial life
Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).

The wetland plant purple loosestrife was imported to North America from Europe. Since its introduction, the loosestrife has spread, which has resulted in a dramatic decline in the biological diversity of native wetland plants. A likely reason for the spread of the purple loosestrife is that it can:_______.
Answer:
Reproduce prolifically.
Explanation:
Purple loosestrife, also known as Lythrum salicaria, is a tall Eurasian plant that spreads quickly. It can attack home gardens and grows mainly in wetlands and ditches. Purple loosestrife can rightly produce over 2 million seeds per plant, which can easily spread by wind and water and also remain viable in soil for several years. The insects and diseases that helps reduce the population of these plants are not found in North America
