As humans we can do whatever to gentically modify trees, but trees take over 100 years to grow back, to fix this, we could prevent unessecary tree cutting and plant new trees for the next generations , they're renewable because they can be replenished over a course of time

Trees are a renewable resource because they grow back. Trees are used for all types of things such as ecosystems or food (berries etc.). It is important for us to keep replanting trees so that the generations beyond have the same advantages as us. It is not renewable however, when they are cut down. This can make some speices become extinct. Even though we need to cut down some trees it is important that at least 1 tree is planted for every 1 cut down. Otherwise, there won't be any trees left... or animals... hopefully this is something like wat u were looking 4... :P

Joan and Mike's teacher show them a picture of an atom and ask them to identify it using the periodic table. Joan says the atom

Goshia [24]

choices are:

Mike is right because the atomic mass of lithium is 6. There are 3 protons and 3 electrons in the atom. 3+3=6

Joan is right because the atomic number of carbon is 6. There are 3 protons and 3 electrons in the atom. The atomic number shows the number of protons plus the number of electrons. 3+3=6

Joan is correct because carbon is a neutral atom. There are the same number of protons and electrons in the atom pictured.

Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.

Li has atomic no. 3 and mass 7. so the correct ans is Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.

Now follow these directions to classify the insect specimens. Start by putting on your gloves and goggles. Then, using the force

The dichotomous key is an important tool to identify the species of living beings, with this tool it was possible to identify the proposed species, however, to understand this question, we need to know that.......

<h3>Dichotomous Key for Insects</h3><h3 />

This dichotomous key is a simplification and is used to find the order of most insects. But as in biology there is always someone or something to deny us, there are insects that defy this order 1.

Start by choosing between one of the two alternatives of option number 1 and go to the indicated number:

- Obvious, membranous wings, sometimes covered with scales or fur: - Wings absent or forewings thick and hiding membranous hindwings: 15
Wings covered with small scales and proboscis-shaped mouthparts: LEPIDOPTERA
- Wings not covered with scales, usually translucent. Mouthpiece is not a proboscis: 3
- With a pair of wings: DIPTERA
- With two pairs of wings: 4
- Long, narrow wings, fringed with fur. Size 5 mm or less: THYSANOPTERA
- Wings not narrow and fringed: 5
- Abdomen with 2 or 3 long filaments. Small hindwings: EPHEMEROPTERA
- Abdomen with short filaments or none. Full-sized hindwings: 6
- Forewings clearly longer and with a larger area than the hind wings: - Four forewings as long as, or nearly as long as the hind wings and with a similar or smaller area: 10
- Wings hairy, opaque, with long palps antennae as long as the body or longer: TRICHOPTERA
- Transparent or translucent wings, hairless, palps short or absent, antennae shorter than the body: 8
- Tarsus with 5 segments, usually with a wasp or bee face: HYMENOPTERA
- Tarsus with 2 or 3 segments, without a bee or wasp face: 9
- Sucking mouthpiece, nozzle starting at the back of the head. Small to large: HOMOPTERA
- Chewing mouthpiece, without beak, length 7 mm or less: PSOCOPTERA
- Head extended ventrally forming beak-shaped structure: MECOPTERA
- Head not extended ventrally: 11
- Very short antennae with thick fur and large eyes: ODONATA
- Antennas not so short. Moderate to small eyes: 12
- Hindwings wider than forewings. Cerci present: PLECOPTERA
- Hindwings as wide or almost as wide as forewings.

With this identification key we can taxonomically classify the 10 insects contained in the question, and with that we can discover the species we are studying.

Taxonomy is an important tool to better understand the species of living beings, their species diversity and their role in ecology.

Some viral infections can lead to the rupture of the lysosome membrane. Which prediction of the effect of this disruption of cel

barxatty [35]

Answer:

<u>Option:(3)-</u>

<em>"Hydrolytic enzymes will be released, which will cause cell death."</em>

Explanation:

<u>Consequences if lysosomes body ruptures:</u>

The lysosomes contains some special enzymes and fluids which are required for the breakdown of the materials inside a cell.And if due to some reasons the membrane of the lysosomes is infected by a viral body, then it will cause the lysosomes to release different enzymes in to the cells cytoplasm. As the lysosomes contains the specialized amount of the hydrolytic enzymes which will cause damage to other organelles inside the cell body.

And this in severe cases some times leads to the death of the living cell, called as necrosis in biological terms.
